# Geometry: Measuring Angles

In this worksheet, students measure angles using the onscreen protractor. Key stage:  KS 2

Curriculum topic:   Geometry: Properties of Shapes

Curriculum subtopic:   Know Angles and Degrees

Difficulty level:   ### QUESTION 1 of 10

Care must be taken when using a protractor.

Top Tips:

The centre must be positioned carefully on the apex of the angle.

The Zero line must be lined up carefully along one arm of the angle.

The position of the Zero will help you decide between the inner scale and the outer scale. Want to understand this further and learn how this links to other topics in maths?
