Using a protractor

I've finally ventured into geometry topics with my latest video:

It shows how to use a protractor to measure angles. I show where the "base line" of the protractor is for three different protractors, and use it to find out the angle measure of different kinds of angles (including a reflex angle).

This is so helpful - thank you! Do you have any tips on how to use a compass as well? I'm a bit rusty here...
