Use formal proof that two triangles are congruent, using the following language:- SSS, SAS, ASA, SAA, RHS as congruent and ASS and AAA as not necessarily congruent. Use diagrams that have the triangles embedded where geometric reasoning must be used to determine the relationship between sides and angles. e.g. prove that the triangles formed by drawing in one diagonal of a parallelogram are congruent. Include examples that make use of the perpendicularity of the tangent and radius of a circlePlay Now
