PLEASEE HELP MEEE

triangle QRS is translated 7 units right then rotated 90 clockwise about the origin . the vertices of tringle Q''R''S'' are Q''( 6,-1),R''(0,-1) and S''(0,-7) find the coordinates of QRS

Answer 1

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)
