There is not enough information for us to know whether or not these triangles are congruent. 1 Launch the Chapter with Career 5. 0 website. SSA stands for Side Side Angle SSA is NOT a criteria for triangle congruence because it is possible for two triangles to have two pairs of congruent You would first prove the two larger overlapping triangles congruent using a postulate like AAS or ASA, and then use CPCTC to state the congruence of the altitudes. Look for your current unit and lesson on In Lesson 22, we begin to investigate criteria, or the indicators, of triangle congruence. After stating the given information, he states that TQ ≅ QS by the definition of segment bisector. 7 - SAS Triangle Congruence 1.
