Rotate ΔPQR 90o counterclockwise about the origin.
P(-5 , 2) ; Q(1 , 5) ; R(3 , -2)
P'(-2 , -5) ; Q'(-5 , 1) ; R'(2 , 3)

P'(-2 , 5) ; Q'(-5 , -1) ; R'(2 , -3)
TRY THIS ONE FOR FUN- We have not talked about a dilation yet- but a dilation can either increase or decrease the size of and object. The center of dilation is the origin. Dilate ΔEFG given a scale factor of 3. (enlarge by a factor of 3) Here are the vertices: E(4 , 9) ; F(-3 , 12) ; G(2 , -8)
E'(4/3 , 3) ; F'(-1 , 4) ; G'(2/3 , -8/3)
E'(12 , 27) ; F'(-9 , 36) ; G'(6 , -24)
E'(7 , 12) ; F'(0 , 15) ; G'(5 , -5)
E'(1 , 6) ; F'(-6 , 9) ; G'(-1 , -11)
