Geometry 7.1: Transformations GOAL: Learn the three major types of geometric transformations

What is a transformation? GOAL: Learn the three major types of geometric transformations 2-dimensional figures can be used to produce new figures. The original figure is called a preimage and the new figure produced is called the image. A transformation is an operation that maps (moves) a preimage onto an image. preimage image

The three basic Transformations: GOAL: Learn the three major types of geometric transformations ReflectionRotationTranslation

REFLECTION GOAL: Learn the three major types of geometric transformations Uses a line (which acts like a mirror), and the preimage is reflected across the line onto an image.

Rotation GOAL: Learn the three major types of geometric transformations A transformation in which a figure is turned about a fixed point.

TRANSLATION GOAL: Learn the three major types of geometric transformations A glide either up, down, left, or right.
