Transformation

An operation that maps a geometric figure call a preimage onto a new figure called the image.

4 Types of Transformations

• Translation

• Reflection

• Rotation

• Dilation

TranSLation

Slide- the figure is moved (slides) but the shape stays the same (congruent)

TranSLation

How do I know which is the original image and which is the new image???

ReFLection

Flip- the image is a mirro of the preimage but reflected over a line on the coordinate plane.

ReFLection

Flip

RoTation

Turn- The geometric figure is rotated or turned about a fixed point.

RoTation

 $180\degree$  turn

Dilation

The image and preimage are the same shape but not the same size.

Dilation

The size is either multiplied by a whole number or by a fraction.
