# Combinations of Transformations

The three basic transformations that can be applied to a shape are as follows:

1. Translation

A translation moves or slides an image. The image can be translated up or down, right or left.

For example:

2. Reflection

A reflection flips a shape over to create a mirror image.

Reflection is a transformation in which a geometric figure is reflected across a line, creating a mirror image.

For example:

3. Rotation

A rotation turns a shape.

Rotation is a transformation in which a figure is turned about a fixed point. Rotation can be clockwise or anticlockwise.

For example:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
