... 2. Prove that every triangle can be divided into 4 isosceles triangles. SOLUTION. We first show that any triangle can be divided into two right triangles, and then that any right triangle can be divided into two isosceles triangles. For the first part note that any triangle will have at least two ac ...

... and c, and let C denote the angle adjacent to sides a and b. Then (using radian measure): cos(c) = cos(a) cos(b) + sin(a) sin(b) cos(C). A spherical triangle is one enclosed by three great circles (each having radius 1 and common centre with the unit sphere). In the illustration on the left, three g ...
