ASA                                                                                                                    Explanation: A shape is congruent when it's all sides are the same SSS but also the shape's side and angle could also be counted as congruent. it can  be like this ASA, SAS, HL, and AAS are a theorem of Congruent but not AA, SS, SSA, AS and AAA this is because They have only two side congruent we don't know the 3rd side. Also SSA is not congruent because we don't know if the unknown side is equal another thing is SSA spelled back word is A## so lets just leave it at that
