Use This Simple Trick to Measure an Angle Using Only a Level It's all about the plumb.

This KS2 maths article explores how an angle is a measure of a turn. Learn how to draw and measure angles using a protractor.

While degrees are familiar and intuitive, after all, we've been using the 360-degree circle since ancient times, radians offer a more natural way to measure angles in higher mathematics.
