Lesson: Congruence of Triangles: SSS, SAS, and RHS Mathematics

Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to prove that two triangles are congruent using either the side-side-side (SSS), the side-angle-side (SAS), or the right angle-hypotenuse-side (RHS) criterion.

Lesson Plan

Students will be able to

recognize that SSS, SAS, and RHS are conditions of congruency but that AAA is not,
recognize whether SSS, SAS, or RHS can be used to prove that two given triangles are congruent,
understand that the condition of congruency for two right triangles is not necessarily RHS,
solve a word problem or a more complex geometric problem using SSS, SAS, or RHS.
