WebIf you have matching sides and angles enough to say the two triangles are congruent, then you can match them (carefully, so the correct angles/sides align) and find out what x is by grabbing it's congruent value. As they get trickier, you will have to combine these approaches to get an answer. Hope that helps! 2 comments ( 13 votes) Upvote Downvote WebIn the following formal proof, you will relate two angles and a nonincluded side of AB to two angles and a nonincluded side of RST. Figure 12.7 Two angles and a nonincluded side of ABC are congruent to two angles and a nonincluded side of RST. Given: Two triangles, ABC and RST, with A ~= R , C ~= T , and ¯BC ~= ¯ST. Prove: ABC ~= RST.
