WebAnd this comes out of angle-side-angle congruency. Well, what does that do for us? Well, if two triangles are congruent, then all of the corresponding features of the two triangles are going to be congruent. In particular, side DC on this bottom triangle corresponds to side BA on that top triangle. So they need to be congruent. WebIf we have a triangle where two sides have unequal lengths, then the angle opposite the longer side has a larger measure than the angle opposite the shorter side. Equivalently, the angle opposite the shorter side has a smaller measure than the …
