Shape and symmetry: To identify right angles

In this lesson, you will recap on the names of different types of angles. We will be looking specifically at right angles today and exploring where they can be found. We will learn what makes an angle a right angle. We will make right angle checkers to help us investigate. We will also be making predictions about the number of right angles in a variety of different shapes.
