Next lesson. Which triangle congruence theorem can be used to prove the triangles are congruent? An included angleis an angle formed by two given sides. Practice: Justify triangle congruence. 1. Triangle Congruence Postulates The first two postulates, Side-Angle-Side (SAS) and the Side-Side-Side (SSS), focus predominately on the side aspects, whereas the next lesson discusses two additional postulates which focus more on the angles. The SSS Postulate tells us, If three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. (Importantly, Side-Angle-Side itself is a postulate in neutral geometry, because you have to start somewhere when comparing triangles.). Save. 2.02 Quiz: Reasoning 1. They are the same shape (and can be called similar), but we don't know anything about their size. This is the currently selected item. SAS (Side-Angle-Side): If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent. Here, instead of picking two angles, we pick a side and its corresponding side on two triangles.
