Question

Segment AB is rotated to form ​ A'B'¯¯¯¯¯¯¯ ​.

The coordinates of point A are (1, 5) and the coordinates of point B are (−6, 4) .

Which clockwise rotation around the origin results in the transformation of ​ AB¯¯¯¯¯ ​ to form​ A'B'¯¯¯¯¯¯¯ ​?

A) rotation of 90
B) rotation of 180
C) rotation of 270

Answer 1

Your answer is B, since it has changed 2 quadrants and the equation for a 180 degree turn is (x,y) --> (-x,-y)
