In this GCSE Mathletics study guide, we'll go through what happens when shapes are reflected, as well as the different centres of rotation and enlargement and congruent shapes. Transformations change the size or position of shapes. Congruent shapes are identical. Scale factors calculate area and volume of similar shapes.

The centre of rotation may not be at the origin.
Rotate the rectangle ABCD 90° clockwise about the point (0,-1).
Each corner of the image A'B'C'D' is the same distance from the centre of rotation as the original shape.
