Chapter 5

Congruent Triangles

In this chapter we will look at relationships within the sides and angles of triangles as well as between two triangles. We will prove triangles congruent using SSS, SAS, AAS, ASA, and HL using a variety of proof formats. We will primarily be working with two-column proofs. We will connect the idea of congruent triangles to composing transformations from Chapter 4. A sequence of rigid transformations maps one triangle onto another triangle.
