PROVING TRIANGLES CONGRUENT

In this unit, you will examine how triangles can be proved congruent. You will explore several postulates related to triangles including the Side-Side-Side (SSS), Side-Angle-Side (SAS) and Angle-Side-Angle (ASA) postulates. You will examine the proof of the Angle-Angle-Side (AAS) Theorem. This unit will conclude with theorems about isosceles and equilateral triangles.
