Question

Given an appoint on a geometric figure (1,2) what is the point when the point is rotated clockwise about the 90 degrees?

Answer 1

When a point (1,2) is rotated clockwise about 90 degrees, the new coordinates of the point can be found by switching the x and y coordinates and changing the sign of the new x coordinate. So the new point after rotating the original point (1,2) clockwise by 90 degrees is (-2,1).
