2. 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

3. 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.)

(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”

4. 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
