Identify Similar Triangles with Proofs Worksheets We can easily identify similar triangles by applying three similarity theorems specific to triangles. These three theorems involve, side-angle -side (SAS), Angle- Angle (AA), and Side-Side-Side (SSS). The three similarity theorems of a triangle depend upon the corresponding parts.
