Question

A triangle has vertices Q (4,5),R(4,0), and S(1,0)

A. rotate 90 degrees ccw about the origin.
B. rotate the triangle 180 about the vertex S.
C. Are the images in parts (a) and (b) congruent? Explain

Answer 1

Well it depends because if it is moving the figure its not changing it. But if its changing the form then it is not congruent. In my opinion I think it isn't changing the figure at all, its just being moved.
