WebSimilar triangles have the same shape but different sizes. In similar triangles, corresponding angles are equal. Corresponding sides of similar triangles are in the same ratio. The ratio … WebThere are three ways to find if two triangles are similar: AA, SAS and SSS: AA AA stands for "angle, angle" and means that the triangles have two of their angles equal. Example: these two triangles are similar: If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°.
WebHow to Solve Similar Triangles. Alright, now that we know the criteria for similarity and the properties of similar triangles, it’s time to solve a couple of examples. Example.
