**What is an invariant point?**

In Transformations, invariant points are points that do not move when you complete a transformations.

**When do invariant points occur?**

This depends on the transformations.

1) Reflection: Invariant points occur if the mirror line touches the shape.

2) Rotation: Invariant points occur when the centre of rotation is on one of the edges or vertices of the shape to be rotated.

3) Enlargement: Invariant points occur when the centre of enlargement is on one of the edges or vertices of the shape to be rotated.

4) Translations: Invariant points cannot occur on a translation as every point moves the same amount.
