Question

to prove the triangles are congruent, which of the following rigid motions would map △ghj to △znp? (1 point) rotation - 90° (clockwise) about point j, then translation along the vector, mapping point h to point z translation along the vector, mapping point j to point p, then rotation 90° (counterclockwise) about point j translation along the vector, mapping point j to point p, then rotation - 90° (clockwise) about point j translation along the vector, mapping point g to point n, then rotation - 90° (clockwise) about point g

Explanation:

To map △GHJ to △ZNP, rigid motions must align corresponding vertices. Assuming J→P (corresponding vertices), translating J to P first positions the base vertex. A -90° (clockwise) rotation about the translated J (now P) would orient the remaining vertices to match Z and N.

Answer:

C. translation along the vector, mapping point J to point P, then rotation -90° (clockwise) about point J
