In this worksheet, students calculate angles at a point and on a straight line. This content is premium and exclusive to EdPlace subscribers. Key stage:  KS 2

Curriculum topic:   Maths and Numerical Reasoning

Curriculum subtopic:   2D Shapes: Circles, Angles and Bearings

Difficulty level:   #### Worksheet Overview

Angles at a point add to 360°.

Angles on a straight line add to 180°.

If we know one of the angles at a point, or on a straight line, we can calculate the other one.

Examples

 At a point: a + 240° = 360° a = 120° On a straight line: b + 160° = 180° b = 20° At a point: a + 45° = 360° a = 315°
