Quick Facts

Lesson: 1: Lines and Angles
Topic: Constructing Angles with a Compass
Domain: Geometry

Every angle here comes from two moves only: step the radius round a circle for 60, and cut an angle in half.

Study Tip

Do not memorise nine recipes. For any angle, ask two questions: is it free from radius steps, and if not, which two angles does it sit between?
