Question

23 triangle fgh is shown on the coordinate plane. triangle fgh is rotated 90° clockwise to create triangle fgh. select one correct answer in each box to complete each sentence. triangle fgh is a congruent b similar but not congruent c not similar to triangle fgh.

Explanation:

A rotation is a rigid - motion transformation. Rigid - motion transformations preserve side lengths and angle measures. Congruent figures have the same shape and size. Since a 90 - degree clockwise rotation is a rigid - motion, the pre - image (triangle FGH) and the image (triangle F'G'H') have the same shape and size. Similar figures have the same shape but not necessarily the same size. Since the size is the same here, they are congruent.

Answer:

A. congruent
