Drawing angles uses a very similar method to measuring angles. If you know how to measure angles, you will pick up drawing them in no time!

You need a:

• protractor
• sharp pencil
• ruler

Draw an angle of 50°.

Step 1: Draw a straight line using a ruler.

Step 2: Place the centre (cross section) of the protractor at one end of the line. This will become the vertex (corner) of the angle. Make sure the line lines up with the base line of the protractor.

Step 3: Look for 50° on the protractor.

There are two lots of numbers on the protractor - on the inside and outside. Look for the zero that is on the same side as the line. It is on the left-hand side and on the outside.

Make a mark where the 50° is on the outside scale.

Step 4: Remove the protractor. Using a ruler, join the mark you made to the end of the line that was in the centre of the protractor.

Draw an angle of 120°.

Step 1: Draw a straight line using a ruler.

Step 2: Place the centre (cross section) of the protractor at one end of the line. This will become the vertex (corner) of the angle. Make sure the line lines up with the base line of the protractor.

Step 3: Look for 120° on the protractor. Since the zero is on the inside scale, look for the 120° that is also on the inside. Create a small mark at this point.

Step 4: Remove the protractor. Using a ruler, join the mark you made to the end of the line that was in the centre of the protractor.

Top tip

Always double check your angle with a protractor once you have drawn in.

This is to make sure that the protractor didn’t move at any point and cause an inaccurate answer.

Drawing angles activity

You will need a piece of paper, pencil and a protractor.

Using a protractor, draw the following angles:

• 130°

• 20°

• 105°

• an acute angle

• an obtuse angle

• a right angle

EXT: Draw five more angles of your choice
