Module 1
Triangle Congruence
What this module is about
This module is about triangle congruence. It will teach you how to prove
that two triangles are congruent by SSS, SAS, ASA and SSS congruent
postulates.
What you are expected to learn
This module is designed for you to:
1. apply the properties of congruence by:
 Reflexive property
 Symmetric property
 Transitive property
2. use inductive skills to prove congruence between triangles
3. show congruence between triangles by:
 SSS congruence
 SAS congruence
 ASA congruence
 SAA congruence
How much do you know
For each pair of triangles, identical marks indicate two pairs of corresponding
congruent parts. Name the congruence postulate which will prove the triangles
congruent.
What you will do
