Curriculum topic:   Geometry: Properties of Shapes

Curriculum subtopic:   Recognise/Find Angles

Popular topics:   Angles worksheets, Geometry worksheets

Difficulty level:   #### Worksheet Overview

In this activity, you will need to find missing angles.

Missing angles on a straight line

Angles on a straight line add up to 180°.

To calculate a missing angle on a straight line, take away the known angle from 180°. Missing angles in a full turn

Angles in a full turn add up to 360°.

To calculate a missing angle in a full turn, take away the known angle from 360°. Missing angles on intersecting lines

All four angles will add up to 360°.

Opposite angles on a cross are equal. A quadrilateral is any shape with four sides.

For example; square, rhombus, trapezium, parallelogram. Let's have a go at some questions.
