See if it's really true, and then prove it! They have two equal sides, but what about their angles? In triangles, sides and their opposite angles are related! 4. Triangle congruence and similarity. Use similarity to find unknown side lengths! Depending on the sides, you can have 0, 1, or 2 triangles! 5. Polygons and quadrilaterals.
