Webb11 jan. 2024 · Triangle congruence theorems (SSS, SAS, & ASA Postulates) Triangles can be similar or congruent. Similar triangles will have congruent angles but sides of different lengths. Congruent triangles will have completely matching angles and sides. Their interior angles and sides will be congruent.

WebbWe can see that the small triangle fits into the big triangle four times. So when the lengths are twice as long, the area is four times as big. So the ratio of their areas is 4:1 . We can also write 4:1 as 2 2:1. The General … WebbTriangles are uniquely determined by specifying three sides ( SSS theorem ), two angles and a side ( AAS theorem ), or two sides with an adjacent angle ( SAS theorem ). In each of these cases, the unknown three quantities (there are three sides and three angles total) can be uniquely determined.
