Rotating a shape and describing a rotation
MA28-03
This lesson is coming soon.
In this lesson
Rotate a shape a given angle clockwise or anticlockwise about a stated centre, and give the full three-part description (centre, angle, direction) of a rotation between a shape and its image.
What it covers
- Rotating a shape clockwise or anticlockwise through a given angle about a marked centre, using a tracing-paper mental model
- Identifying the centre, angle and direction of a rotation from a shape and its image
- Stating that anticlockwise is the positive convention
- Giving the full three-part formal description: the word 'rotation', the angle and direction together, and the centre

On the specification
| Board | Spec | Statement |
|---|---|---|
| Edexcel IGCSE 4MA1 | F5.2A | Understand that rotations are specified by a centre and an angle |
| Edexcel IGCSE 4MA1 | F5.2B | Rotate a shape about a point through a given angle |
| Edexcel IGCSE 4MA1 | F5.2C | Recognise that an anti-clockwise rotation is a positive angle of rotation and a clockwise rotation is a negative angle of rotation |
| OCR GCSE J560 | 9.01b | Rotate a simple shape clockwise or anti-clockwise through a multiple of 90° about a given centre of rotation. |
| Cambridge IGCSE 0580 | C7.1 | Transformations |
| Cambridge IGCSE 0580 | E7.1 | Transformations |
| AQA GCSE 8300 | G7 | Identify, describe and construct congruent and similar shapes, including on coordinate axes, by considering rotation, reflection, translation and enlargement |
| Edexcel GCSE 1MA1 | G7 | Identify, describe and construct congruent and similar shapes, including on coordinate axes, by considering rotation, reflection, translation and enlargement (including fractional scale factors) |
| Eduqas GCSE C300 | FG7 | Identify, describe and construct congruent and similar shapes, including on coordinate axes, by considering rotation, reflection, translation and enlargement (including fractional scale factors) |
| Eduqas GCSE C300 | HG7 | Identify, describe and construct congruent and similar shapes, including on coordinate axes, by considering rotation, reflection, translation and enlargement (including fractional and negative scale factors) |
For teachers
This GCSE Maths lesson teaches rotating a shape and describing a rotation. By the end, students should be able to rotate a shape a given angle clockwise or anticlockwise about a stated centre, and give the full three-part description (centre, angle, direction) of a rotation between a shape and its image. It works through two worked examples and the mistakes examiners report.
