transformations (Translations). . . Today’s Lesson: What: transformations (Translations). . . Why: To introduce transformations and begin performing translations .

What is a transformation?? A transformation refers to a specific way a figure in geometry is either changed or __________________ to create a different image. moved 4 Types of Transformations: Translation-- 2) Reflection-- is a slide. A AI is a flip. A AI

Let’s focus on translations . . . Rotation-- Dilation-- is a turn. A AI is a change in size. A AI Let’s focus on translations . . .

We call this “A___________.” First things first . . . We call this “A___________.” prime A AI PRE-IMAGE (before) IMAGE (after)

Perform the following translations: Translate the figure (2, -4): This means two units to the RIGHT and four units DOWN!

Perform the following translations: Translate the figure (-3, 1): This means three units to the LEFT and ONE unit up!

Perform the following translations: Translate the figure (-4, -4): This means four units to the LEFT and four units DOWN!

Perform the following translations: Translate the figure (6, -2): This means six units to the RIGHT and two units DOWN!

If point A is located at (2, 5) and is translated three units to the left and two units up, where would A1 be? If point A is located at (-4, 2) and is translated five units to the right and four units down, where would A1 be? RIGHT or LEFT changes X!! UP or DOWN changes Y!! (-1, 7) RIGHT or LEFT changes X!! UP or DOWN changes Y!! (1, -2)
