Proving Triangles Congruent (09:40) Using Congruent Triangles (03:13)
Review: Triangles (01:20)
PROVING TRIANGLES CONGRUENT
In this unit you will examine how triangles can be proved that triangles are congruent. You will explore postulates and theorems related to triangles including the Side-Side-Side (SSS) postulate, Side-Angle-Side (SAS) postulate, the Angle-Side-Angle (ASA) postulate, and the Angle-Angle-Side (AAS) theorem. This unit will conclude with theorems about isosceles and equilateral triangles.
