... Things to remember: For any triangle, the sum of the lengths of any two sides is greater than the length of the third side. | AND | for any triangle, if two sides are not congruent, then the larger angle is opposite the longer side 1. Can a triangle have side lengths 22, 33, and 25? Why or why not? ...
