# Review understanding and identification of right angles

I can recall understanding and identification of right angles.

## Lesson details

### Key learning points

- A right angle is a square corner.
- A right angle is a quarter turn.
- There are right angles in buildings and the environment.

### Common misconception

Right angles are only where a horizontal and vertical line meet to create a square corner.

Ensure pupils are shown a wide range of right angles in a variety of orientations and contexts so that pupils can better generalise the features of a right angle.

### Keywords

Right angle - A right angle is a quarter of a full turn. It can be known as a ‘square corner’.

You can use different angle tools to measure either the inside of a right angle (folded paper) or the outside of a right angle (angle strips). Ensure pupils are familiar with using both tools to find right angles in their own settings.
