Identifying Translations, Reflections, and Rotations: Sample FAST Questions

Given a figure and its image, 8th graders name the single transformation that produced it: a translation slides, a reflection flips, and a rotation turns. All three are rigid motions, so the image stays congruent to the original figure.

How the FAST tests this benchmark

The FAST shows a preimage and an image on a grid and asks multiple choice or matching questions naming the transformation. A reflection across a vertical line and a 180 degree rotation can look alike, so students check whether the orientation was reversed.

Skills students need

Identify a translation from a preimage and image
Identify a reflection and the line it was reflected across
Identify a rotation and its angle
Explain why rigid motions preserve congruence
