Homework Help: math

Posted by robert on Saturday, December 1, 2007 at 10:49pm.

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). In rotation, the coordinates get switched. All I just did was switch the numbers and signs. Is this right?
