Simple Math Tutorial How to Measure Angles

----------------------------------------------------
Angles are a measure of how far something has turned, or pivoted around a point. Measuring them requires an instrument called a protractor. There are both full-circle and half-circle protractors. In this video we're using half-circle ones, but you can use whatever you have to hand.

There are three steps involved in measuring an angle:
1. Aligning the vertex with the center of the protractor.
2. Making sure one arm is lined up with a zero-degree mark on the protractor.
3. Reading the position of the third angle to determine the angle size.

The above video covers what this actually looks like.
