Learning About Congruent Triangles

There are three common methods used to determine if two triangles are congruent.

One way is "Side-Side-Side" (or SSS): in this case the lengths of all corresponding sides are equal.


Another method is "Side-Angle-Side" (or SAS): this is where two corresponding sides and the included angle are equal.


For "Angle-Side-Angle" (or ASA): two corresponding angles and the included side are equal.
