17/09/2018 · Two triangles can be proved similar by the angle-angle theorem which states: if two triangles have two congruent angles, then those triangles are similar. This theorem is also called the angle-angle-angle (AAA) theorem because if two angles of the triangle are congruent, the third angle must also be congruent.... The two triangles below look like they could be similar but we cannot say for sure unless we know more about the length of the sides and/ or the angles within the triangle. To find if triangles that are similar we must compare corresponding sides and/ or corresponding angles.
