9.2 REFLECTIONS

Objective: To Identify and find Reflections of figures.

Vocabulary: Transformations Preimage Reflection

Solve It:

TYPES OF TRANSFORMATIONS Reflections – The flip of a figure over a line to produce a mirror image. Rotation – A geometric turn of a figure around a fixed point. Translation – The slide of a figure from one position to another. Dilation – A transformation that alters the size of a figure, but not its shape.

Preimage to Image B’ A’ C’ B Its matching point on the corresponding figure is called its image. D’ A C D Each point on the original figure is called the Preimage
