    Pentagon ABCDE is shown on the coordinate plane below. If pentagon ABCDE is rotated 180° around the origin to create pentagon A’B’C’D’E’, what is the ordered pair of point C’? (-5, 2) (5, 2) (2, -5) (-2, 5)

    one way to do this is put one leg of a compass on the origin and the other leg on point C and draw a circle. 180 degrees will be 1/2 of the circle. |dw:1364930145467:dw|
