(More about triangle types) Therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier. When the side of a triangle is determined, and the two angles from which the other two sides point, the whole triangle is already determined, there is only one point, the third vertex, where those other sides could possibly meet. Example 1: If two altitudes of a triangle are congruent, then the triangle is isosceles. ... Quiz 3 Thursday 1/30 Triangle Congruence, Parallelograms Triangle Proofs Worksheets.
