# IM1 G-CO-4 Lesson 1 Translations Moving an Object IM1 G-CO-4 Lesson 1 Translations Moving an Object In 2 Dimensions Mr. Deyo G.CO.4 Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments. Title: IM1 G-CO-4 Lesson 1 Translations Date: Learning Target By the end of the period, I will create a definition of translation in 2 dimensions and apply that definition to a given object. I will demonstrate this by completing FourSquare Notes and by solving problems in a pair/group activity. Home Work 1-2-3:

TRANSLATION (Slide): moves all points in a plane a given direction and Translations PRESERVE: Size Shape Orientation a fixed distance The blue pentagon is the PRE-IMAGE and the green pentagon is the IMAGE. How would you describe the translation? + -

The IMAGE has moved ___ units right / left and + ___ units up /down from the PRE-IMAGE. <__, __> Problem A Triangle JKL is the PRE-IMAGE and Triangle PQR is the IMAGE. How would you describe the translation? + - The IMAGE has moved ___ units right / left and + ___ units up /down from the PRE-IMAGE.

<__, __> Problem B Notes: Transformation Notation: ABCDE C B D Pre-Image: original figure (Use prime notation) C
