After a triangle is rotated 180 degrees, its vertices are at (4,1),(1,4), and (5,8). What were the coordinates of the vertices before the rotation? I think the answer is (1,4), (4,1),(8,5). Is this right?

A square has rotational symmetry because it can be rotated 180 degrees so that its image matches the original. Your friend says the angle of rotation is 180 divided by 4 = 45 degrees. What is wrong with this statement?
