Plot the following points on graph paper and connect them in the order given. Then connect points A and D.
A(-3,4), B(1,6), C(5,-2), and D(1,4)
If ABCD is rotated 90° clockwise (O) about the origin to form A'B'C'D', what
are the coordinates of the vertices of A'B'C'D'?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
