What are the Congruence Shortcuts?

Side-Angle-Side Triangle Postulate (SAS)
If two side of a triangle and the included angle are congruent to the two sides of another triangle and its included angle, then the two triangles are congruent.

 

• The congruent angle must be between the congruent sides.
• Triangles are congruent if any two sides and their included angle are equal in both triangles.
