ANGLES & SHAPES
HOW TO DRAW A RIGHT ANGLE
1. Look at the picture below of a protractor. You will see that there
is a right angle marked on it. The important line is the 90° line.
2. Draw a base line. Make it about 6 cm long.
3. Put the centre of the protractor on one end of the base line.
4. Find the 90° line on the protractor, mark it and join this point to
the end of the base line. You have now drawn a right angle.
