Words to remember

Translation

Translating a shape means to move it

When a shape is translated it does not rotate or change shape

Every point on the shape move the same distance in the same direction

Reflection

Reflecting a shape simply means to flip it over a mirror line.

Each point in the shape is moved to the other side of the mirror line but remains the same distance away from the line.

Rotation

Rotating a shape means turning a shape about a point.

We measure rotations in degrees like angles

We can rotate a shape clockwise and anti-clockwise
