... by arcs of great circles, and the area that is enclosed within. 1. When you consider the intersection of three distinct lines, how many sections have you now divided the sphere into? Note: From now on you can restrict your focus to just the smallest of the eight triangles. 2. In the Euclidean plane, ...

... Using geometry and algebra, we can find the values for some special angles very quickly. The angles that have terminal sides on an axis are called “quadrantal angles” and can be found using any value for r. Consider a 90° angle. It looks like this: Since the point is not to the right or the left, th ...
