WebWhen two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding … 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°.
