On the graph, trapezoid a has rotated 180 degrees about the origin. compare the areas of the trapezoids. justify your answer. a) the areas may or may not be the same because the scale is not given. b) the area of trapezoid a is greater than trapezoid a'. a rotation decreases the size of the original polygon. therefore, the area is not preserved. c) the area of trapezoid a' is greater than trapezoid a. a rotation increases the size of the original polygon. therefore, the area is not preserved. reactivate d) the areas are equal. a rotation is a rigid transformation, which does not change the size of the original trapezoid. therefore, the area is preserved.
