One change which occurs when using wedged squares is that for any obtuse triangle there are now three largest
wedged squares instead of just one inscribed square (compare Figures lc and 3).
Another result from MPYG which we will need below is the calculation
of the length of the side of a wedged square on a triangle side with no obtuse
angles. If we denote the length of the side of a wedged square on side a of a
triangle by s a and the height of the triangle from side ahyha, then we have
•„ — ——, where side a has no obtuse angle.
