Official Curriculum Content Description:

describe and perform translations, reflections and rotations of shapes, using dynamic geometric software where appropriate; recognise what changes and what remains the same, and identify any symmetries

Worked Examples (1)

Example 1Transformations of Drawn Shapes on a Plain Grid
Shape AA and its transformed image Shape BB are shown on the plain grid below. Shape AA contains an interior angle of 85∘85^\circ. When Shape AA is translated to form Shape BB, what is the size of the corresponding angle in Shape BB in degrees?
Shape AShape BNSEW
Correct Answer:85°85°
Accepted: A unit is optional (degrees, deg, ° all accepted).
Worked Solution:
1. Rigid transformations (translations, reflections, rotations) preserve all angle sizes. 2. Therefore, the corresponding angle in Shape BB is also 85∘85^\circ.
