  • There are three ways to prove similarity:

    1. If two triangles have two angles equal to each other, then the triangles are similar (when two angles are equal then all three angles must be equal). We use \(AAA\) to show this relationship
    2. If two triangles have three pairs of sides in the same ratio, then the triangles are similar
    3. If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar. We use the letters \(SAS\) to show that relationship.
    Watch the video to see these three postulates (statement that is taken to be true without proving it) in action.
