Question

Triangle QRS is translated 7 units right then rotated 90 degrees clockwise about the origin. The vertices of the triangle AFTER these transformations Q'' (6,-1), R''(0,-1), and S''(0,-7). what are the vertices of the ORIGINAL triangle

Answer 1

Hi, this question has been asked before! Here's the answer they gave:

The task is to find the original coordinates with the transformed ones given, so you have to apply the inverse of the stated transformations.

Q"( 6,-1),R"(0,-1) and S"(0,-7)

-> rotate 90 anti-clockwise

Q'(1,6), R'(1,0),S'(7,0)

-> translate left by 7 units

Q(-6,6), R(-6,0), S(0,0)

Credits to them for the answer.
