Question

Choose either the SSS Postulate or the SAS Postulate and explain in your own words how you use that postulate to prove two triangle are congruent.

Answer 1

Let's use the SAS postulate! SAS means Side, Angle, Side. I would sometimes write this the other way and get in trouble, haha.
It technically means if a triangle that has a congruent angle between two congruent sides, it means it is congruent. Here is a picture.
