WebJan 24, 2011 · Rotating a vector 90 degrees is particularily simple. (x, y) rotated 90 degrees around (0, 0) is (-y, x). If you want to rotate clockwise, you simply do it the other way around, getting (y, -x). Share Improve this answer Follow answered Jan 24, 2011 at 8:56 Sebastian Paaske Tørholm 49k 10 99 118 47 +1. WebR (x,y) ⇒ R' (-x,-y) (i). A (3,4) ⇒ A’ (-3,-4) (ii). B (2,-7) ⇒ B’ (-2,7) (iii).C (-5,-1) ⇒ C’ (5,1) Answer: A’ (-3,-4), B’ (-2,7), and C’ (5,1) are the 180 degrees rotated points of A (3,4), B (2.-7), and C (-5,-1) Example 2: Rotate a line AB having ends as A (4,5) and B (-1,2) by 180 degrees. Solution: To find: Rotate a line AB by 180 degrees.
