Answer:
Explanation:
(x,y)→(-x,-y) (180° about the origin)
1.p(-3,2) ,in the second quadrant
P(-2,-3) is in 4th quadrant.
in the clockwise it is rotation of 270° about the origin.
2.
Q(-4,-5) is in 4th quadrant.
Q(4,5) is in 1st quadrant.
so it is 180° rotation in the clockwise direction.
3.
R(1,7) is in 1st quadrant.
R(7,-1) is in 4th quadrant.
Hence it is 90° rotation about the origin in clockwise direction.
