*Transformations *

**L.O – To be able to understand all 4 transformations, translation, enlargement, rotation and reflection and carry them out.**

There are 4 transformations you need to know about

- Translation
- Enlargement
- Rotation
- Reflection

**Translation:**

**Translation is the movement of an object up, down or from side to side.**

The shape, size and direction does not change.

This vector tells us the object has moved 4 spaces to the right and 2 spaces up.

A negative sign (-) means the movement is to the left/down.

Note horizontal movement (along x axis) is stated at the top of the vector and vertical movement (along y axis) at the bottom.

Triangle abc has been translated by

It has been translated 3 spaces to the right and 2 spaces down

Note every vertex is moved in the same way!

**Enlargement:**

Enlargement is simply when an object has been made bigger – it’s size changes.

With enlargements, we need to know the scale factor and centre of enlargement.

- Scale factor = tells us by how much the object has been enlarged
- Centre of enlargement = where enlargement is being measured from

Centre of enlargement = (1,1)

Note, a fractional scale factor means the size of the object has been reduced

A negative scale factor means the enlarged object is drawn in the opposite direction.

**Rotation:**

With rotations, we need to know the angle the object has been turned, direction and the centre of rotation.

- Angle turned e.g. 90°, 180° etc
- Direction – clockwise or anticlockwise
- Centre of rotation – where the object has been rotated from

Triangle ABC has been rotated 90°, clockwise about the origin.

**Reflection:**

With reflections, we need to know what the mirror line is in which the object has been reflected.

When an object is reflected, the object and its image are always the same perpendicular distance from the mirror line.Remember, perpendicular = at right angles to

Triangle ABC has been reflected in the mirror line y=x

Remember, x = … lines are vertical lines

y = … lines are horizontal lines

Also, make sure you know what the line y= -x looks like
