Triangle
Congruence by SSS
and SAS
You can prove two triangles are congruent
without having to show all corresponding
parts are congruent.
Side-Side-Side (SSS) Postulate
If the three sides of one triangle are
congruent to the three sides of another
triangle, then the two triangles are
congruent.
You can also prove two triangles congruent
by using relationships between a pair of
corresponding sides and an included angle.
The word included refers to the angles and
sides of a triangle as shown below.
A is the included angle of sides BA and AC.
Side BC is the included side of B and C.
Side-Angle-Side (SAS) Postulate
If two sides and the included angle of one
triangle are congruent to two
corresponding sides and the included
angle of a second triangle, then the two
triangles are congruent.
