Protractors are fun and easy to use

Have a look at this animation (press the play button) to see how to make a neat angle using a protractor and ruler:

Protractors usually have two sets of numbers going
in opposite directions.

Be careful which one you use!

When in doubt think "should this angle be bigger or
smaller than 90° ?"

Try to measure the angles A, B, C
and D inside this shape.

Be careful which angle you read from
the protractor.

Hint: if you get them all correct,
they will add up to 360°

The answers are ... no, that would
spoil the fun!
