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 [icon]/images/ggb/toolbar/mode_translatebyvector.png[/icon] by directed line segment v. [br]2) Rotate [icon]/images/ggb/toolbar/mode_rotatebyangle.png[/icon] the image ____ degrees [b]clockwise[/b] around point D. (A' is on top of D) [br]3) Reflect [icon]/images/ggb/toolbar/mode_mirroratline.png[/icon] 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!
