## Drawing Angles – A Comprehensive Guide

If you are after a guide explaining how to draw different angles, you are in the right place. In this text, you will learn about drawing different angles with a protractor. We will present you with some guided practice on how to do that, and then will answer some of the most frequently asked questions about drawing angles. Feel free to check out our drawing angles with a protractor worksheet to consolidate your skills.

## Types of Angles

Before delving into the drawing aspect, it’s crucial to familiarize yourself with the different types of angles.

Acute, obtuse, right, straight, reflex, and full angles each possess unique properties and appearances, knowing their definitions will help you to draw them too.

### Acute Angles

Acute angles are small, sharp angles that are less than 90 degrees. When drawing, they appear narrow and pointed.

### Obtuse Angles

With measures between 90 and 180 degrees, obtuse angles are wider and open.

### Right Angles

At precisely 90 degrees, right angles form a perfect corner, often observed in squares and rectangles.

### Straight Angles

The easiest angle to draw, straight angles line up flatly, measuring exactly 180 degrees.

### Reflex Angles

These angles are larger than 180 degrees but less than 360, creating a sort of 'loop'.

### Full Angles

A complete circle or 360 degrees, full angles are seldom used but essential to know.

## Tools for Drawing Angles

It is impossible to draw angles accurately without precision tools. Let’s review some of them.

• protractors: This semicircular tool is indispensable for measuring and drawing angles. Place it on the angle's vertex, align it properly, and you can read the angle's measure.

• compasses: Compasses assist in drawing angles and circles with precision, making them an invaluable tool for creating accurate angles and bisectors.

## Drawing Angles – Guided Practice

1. Identifying the Angle – before even picking up your pencil and protractor, identify what angle you will need to draw, follow this table to quickly remind yourself what angle you will have to draw:

Degrees Type of Angle
1–89 acute angle
90 right angle
91–179 obtuse angle
180 straight angle
181–359 reflex angle
360 full angle

2. Drawing the First Side – now that you have identified how roughly your angle will look, draw the first side of the angle. The easiest way is to draw one horizontal line. 3. Using the protractor – pick up the protractor and place it on the angle's vertex. You should be able to read the numbers that are written on the protractor. Align the baseline of your protractor and the first side of your angle, it properly, and you can read the angle's measure.

If you are drawing an acute angle, find the number representing the needed degrees, which should be below 90. Place a dot next to the necessary number. 4. Drawing the Second Side – remove the protractor and pick up a ruler. You will need to connect the vertex of the angle and the dot you have left on paper after using the protractor. Draw a straight line between these points. And here you are, you are done with drawing your angle!  5. Check – the final step in drawing angles using a protractor is to make sure that the angle you drew actually looks like the one you needed to draw.

Remember that acute angles are pointy, whilst obtuse are broad. ## Drawing Angles – Conclusion

### TranscriptDrawing Angles

Nico and Nia are playing mini-golf. Nico is figuring out the angle he needs to hit the ball in order to get a hole in one. If he understands the angles, he can get the perfect putt. : “Drawing Angles” A protractor is the tool we use to make angles. The baseline helps draw straight lines and line up the angles. The inner and outer scales are what we use to measure the degrees. REMEMBER, we use the set of numbers on the scale that are facing the SAME DIRECTION as our angle opening. Let’s see how we can help Nico use the protractor to draw the angle as he lines up his putt. If he putts a one hundred eighty-degree straight angle through the tunnel, he will make this shot. First, he'll use the tunnel as the MIDDLE of the angle and make a dot here for the VERTEX. Next, he'll use the straight edge to draw a LINE SEGMENT from the vertex to the ball and from the vertex to the cup. Nico swings and(...)HOLE IN ONE! WE DID IT! This next course is challenging because he must hit the ball off the statue to go into the cup. Using the statue as the point where the line segments meet, let’s help Nico draw this angle. What should we do first? First, we’ll make a dot to represent the vertex. Then we need to line up the vertex and the ball. Draw a line segment to connect these two points. Now line this up with the zero on the OUTER SCALE of the protractor. Follow the outer scale until it intersects with the cup. How many degrees is this angle? This angle is ONE HUNDRED FIFTEEN degrees. Make a dot at this point just above the protractor. Move the protractor so the straight edge lines up from the vertex to the mark(...) made at one hundred fifteen degrees. Draw a line segment to connect these two points. If Nico follows our angle, he will make the hole in one! YES! This next hole looks like a right angle. Let's draw it to see if it is ninety degrees. We'll use the pinwheel as the vertex. First, make a dot here. Using the straight edge, draw a line segment from the vertex to the ball. Now we will line up with the zero on the outer scale. What do we need to do next? We follow the outer scale until it intersects with the cup. Here, we make a dot above the protractor at NINETY degrees. Now we return to the straight edge and line it up from the vertex to this point. We'll draw a straight line to connect. Did we make a right angle? Nico's putt follows the right angle and he has DONE it again! The last hole of the game is a thirty-degree angle. Let’s draw it so Nico knows what to do. The tower of the castle is where the two line segments meet, so we’ll draw the dot there to show the vertex. Draw the line segment from the vertex to the ball. What should we do next? Place the baseline along this line segment where it lines up with zero. On the outer scale, look for thirty degrees Place a mark at the thirty-degree point because this is where the cup intersects. Then we’ll use the straight edge to connect these points. Remember(...)we can use a protractor to draw angles. First, make a vertex and use the straight edge to draw a line. Then, place the center of the baseline on the vertex and line up with zero. Next, find the given measurement along the proper scale and mark that spot. Finally, use the straight edge to connect the vertex to the measured spot. [Nico hits the ball into the hole and the ball pops back out. Nico looks confused and looks into the hole; Nia is in there. She hops up and high fives Nico.] Nico scored a perfect game by drawing angles to figure out how he should hit the ball! Now THAT deserves a high five!

• ### How do you draw an angle?

Hints

We need to draw a baseline before we can draw the angle.

Look at the picture. The baseline has been drawn, what happens next?

Solution
1. First, make a vertex and use the straight edge to draw a line.
2. Then, place the center of the baseline on the vertex and line it up with zero.
3. Next, find the given measurement along the correct scale and mark that spot.
4. Finally, use the straight edge to connect the vertex to the measurement spot.
• ### Will Nico make the shot?

Hints

Has Nico found the correct spot on the protractor to draw the angle?

Does the angle line up with the hole (not the top of the flag)? If it doesn't the angle must be incorrect.

Solution

Here are the correct angles.

• The first angle and the third angle Nico drew were correct.
• He lined up the protractor and marked the correct spot needed.
• The second angle and the fourth angle Nico drew were incorrect.
• The spots he marked on the protractor were not the correct ones to make the hole meaning the ball rolled past.
• ### Can you match the angles?

Hints

One line is drawn along the baseline. Look at the number where the other line crosses the protractor.

The angle being drawn here is 70°.

Solution
• The first angle drawn was 90°. We can see the line pass through the 90° mark on the protractor. It is a right angle.
• The second angle drawn was 180°. We can see the line pass through the 180° mark on the protractor.
• The third angle drawn was 30°. We can see the line pass through the 30° mark on the protractor.
• The fourth angle drawn was 110°. We can see the line pass through the 110° mark on the protractor.
• ### Can you label these angles correctly?

Hints

Is the zero on the baseline? If it is then look at which mark on the protractor the line goes through, this is the angle.

Read the number on the curved edge of the protractor where the line passes through.

Sometimes it might be halfway between two numbers. For example, the angle drawn here is 55° as the line passed through the 55 mark on the protractor.

Solution

Here are the angles.

Each angle

• had zero lined up on the baseline
• had a mark made at the given measurement on the curved edge of the protractor
• had the line drawn through that mark using the straight edge of the protractor

• ### Where should Nico draw the line?

Hints

Which number are we looking for on the protractor? What angle does Nico need to make the hole in one?

Look for the given angle starting from zero, where the ball is.

The dotted line shows the angle Nico needs to make.

Solution

Nico needed to make a 35° angle to get the ball in the hole so 35° needed highlighting on the protractor.

If we were drawing this angle, this is where we would make a mark before using the baseline edge to draw the line.

• ### Nia's Golf Course

Hints

Which part of the protractor do you use to draw a line?

Which number does the line pass through to get to the hole?

Solution

Nia decided there would be a tree obstacle on the first hole. To draw the angle she needs to first make a vertex by the obstacle and use the straight edge of the protractor to draw a line from it to the starting tee.

Nia then looked to see where the hole is. She knew she had to make a mark next to the number that lined up with the hole.

Nia then used the straight edge of the protractor to draw a line from the vertex at the tree to the hole.

The players on this hole will need to make a shot with an angle of 120° to get a hole in one!
