Ch. 10 hw

I learned that in ch. 10 all about the theorems and all of the circles. This can be applied to real life as in sailing. When they did not know how to get to on are suck as going to England then to Norway then to Iceland. They use to have to go to Iceland back to Norway then England. With the use of angles and the Pythagorean theorem. They saved time and money. One question i still have is how you get some of the angle measurements.
