Question

Identify the transformation from the original to the image.

Original ABCD: A(-2, 5), B(1, 4), C(1, 1), D(-2, -1)
Image A'B'C'D': A'(5, 2), B'(4, -1), C'(1,-1), D'(-1,2)
A. Dilation B. Reflection C. Rotation D. Translation​

Answer 1

Answer is C. Rotation

90° clockwise rotation: (x,y) becomes (y,-x)

A ( -2, 5) ➡️ A’ ( 5, 2)

All 4 points follow this same rule
