We will represent1 and describe2 Transformations. Learning Objective What are we going to do? What does represent and describe means ___________. CFU We will represent1 and describe2 Transformations. Activate Prior Knowledge Pair-Share: Describe the transformation next to the appropriate coordinate notation. X-Value = Horizontal Left (-) / Right (+) Y-Value = Vertical Down (-) / Up (+) Students, you already know how translate coordinate points. Today, we will learn how to represent and describe different types of Transformations. Make Connection 1 to show or describe something. 2 how something is done Vocabulary

Concept Development A transformation is a change in the position, shape, or size of a figure. A rigid motion (or isometry) is a transformation that changes the position of a figure without changing the size or shape of the figure. Translations, reflections, and rotations are rigid motions. Not rigid (does not preserve length and angle measure.) CFU (2, 3) (0, 0) (-6, 6) (-1, 1) On your whiteboard, describe what is Transformation, Rigid Motion, and Not Rigid is: Transformation is_______________? Rigid Motion is_______________? Not Rigid is __________________? CFU (read as “A prime”). (changed) (original) “before”

Find the unknown coordinates for the transformation. Skill Development/Guided Practice Find the unknown coordinates for the transformation. +2 -5 Is the transformation a rigid motion? YES! Translation. On your whiteboard Use coordinate notation to describe the transformation of The first one is done for you. +5 +1 1 -1 5 -2 Describe the algebraic rule for X + 5 Y + 1
