Calculate the distance between the midpoints.  Then try using facts about triangles to show that the angles of your rectangle are 90 degrees

(a,2b)

anonymous · Answer

ok consider the triangle formed by ZBC and the length of each side of the triangle.  Are there any triangle properties that you know that can help you figure out all the angles?
