Two polygons of any type can be congruent. In this topic, however, you will focus only on triangles. Two triangles are considered to be congruent if they have corresponding sides and angles of equal measure. The word corresponding refers to the same location in each triangle. In this topic, you will explore the Side-Side-Side (SSS) and Side-Angle-Side (SAS) Postulates, which will help you determine if triangles are congruent.

Essential Questions

• How can you use the SSS Postulate to show that two triangles are congruent?
• How can you use the SAS Postulate to show that two triangles are congruent?
