We give an outline for this argument [6], the details are left to
you to fill in. (See the Appendix.)
Looking at right triangle ACGF in Figure 6, we have tanZC = - j - . Make the substitution tanZC =
solve this equation for Sj,. You can then verify that the formula given above for s^, holds.
Now we look at two examples of obtuse triangles, and compare the sizes of their largest wedged squares. The
results may be a little surprising
