CHAPTER 4 SECTION 2 Triangle Congruence by SSS and SAS

Objective Students will learn to prove two triangles congruent by SAS and SSS.

Postulate 4-1 SSS If three sides of one triangle are congruent to three sides of another triangle then the two triangles are congruent.

Turn to Page 227 Look at Problem 1 Try the “Got It” problem for that example.

Postulate 4-2 SAS If two sides and their included angle of one triangle are congruent to two sides and their included angle of another triangle, then the two triangles are congruent.

Turn to Page 229 Look at Problem 2 and Problem 3 Try the “Got It” problems on this page.

Turn to Page 230 Try Problems #1-7 on your own.
