# MA460 Homework Discussion

Back to Prof. Walther MA460 page.

I finally figured out the the 2nd problem in our 2nd quiz. Make another radius that goes to the top point. Than you have 2 isoscles triangles. So a bunch of congruent angles. Than look at the now big triangle made up of the 2 smaller triangles. Add up those angles to 180 degrees. Substitute the congrent triangles shown earlier, than you left with 2 angles that add to 90 degrees. What helped me here is to draw on sketchpad.
