2. NOT THE OTHER ONE.. SSS ASA SAS
We have learned about Congruent Polygons
Congruency Statements lead to corresponding angles and sides
Congruent simply means the same size and shape
We will now expand this to study Congruent Triangles
We will use three acronyms……….
SSS
ASA

3. Congruent Triangles
If two figures are exactly the same size and shape, they are congruent.
Two triangles are congruent if the following corresponding parts of two triangles are congruent.
Three Sides (SSS)
Two angles and the included side (ASA)
Two sides and the included angle (SAS)

4. Example
Determine whether the triangles are congruent. If so, write a congruence statement and tell why D B C A E
