## Types of Transformations

Transformations are operations that change the position and sometimes the size of a shape.

### Reflection

• A reflection is when a shape is reflected by a line.
• The perpendicular distance from each point in the reflected shape to the line of reflection is the same as the distance for the corresponding point in the original.

• The perpendicular distance from each point in the reflected shape to the line of reflection is the same as the distance for the corresponding point in the original.

### Rotation

• A rotation is when a shape is rotated around a certain point.
• The distance from each point in the rotated shape to the centre of rotation is the same as the distance for the corresponding point in the original.

• The distance from each point in the rotated shape to the centre of rotation is the same as the distance for the corresponding point in the original.

### Translation

• A translation is when a shape is moved from one position to another.
• The orientation of the shape is not changed by a translation.

### Enlargement

• An enlargement is when a shape is made bigger or smaller.
• The lengths of the shape's sides change but the angles and the ratio between the side lengths does not.
