SAS stands for "side-angle-side." A "postulate" is something that is assumed true without anyone needing to validate it. Let''s find out why the SAS postulate is so useful:
The SAS postulate states that if one triangle''s two sides and included angle are congruent to a second triangle''s two sides and an included angle, then both triangles are congruent.
But what exactly is congruence? This is essentially just another way of saying "equal" in the world of geometry.
Consider these two triangles:
We can see that the SAS postulate applies in this situation. Therefore, the two triangles are congruent.
The formula for the SAS postulate is:
