Formula for 90 degree rotation
WebThe angle measure is a little closer to 180\degree 180° than to 90\degree 90°. We could split the circle into more equal parts to get a closer estimate. We might estimate that the angle is around 150\degree 150° to 160\degree 160°, but we'd have to measure to be sure. 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.
