13.3 Translate, Rotate, Reflect

Mai suspects triangle ABC is congruent to triangle DEF. She thinks these steps will work to show there is a rigid transformation from ABC to DEF.

1) Translate Toolbar Image by directed line segment v. 2) Rotate Toolbar Image the image ____ degrees clockwise around point D. (A' is on top of D) 3) Reflect Toolbar Image that image over line DE (B"A" is on top of DE)

Create each image and write the angle of rotation needed for step 2 below (just write the number!)

Remember! The rotation is STEP 2, the blue triangle won't be on the green triangle yet. You still need to reflect!
