Angles: types of angles: Part 1

In this first of two lessons, students explore ways to compare angles and recognise the names of different types of angles, including right, acute, obtuse, straight, reflex and revolution.

In a follow-up lesson, Angles: chalk design, students create their own chalk designs in the style of a stained-glass window that includes different types of angles.
