We do not need to use transformations to prove these triangles are congruent because the ​ (a)   criteria is met.

• SSS (side-side-side)
• AAA (angle-angle-angle)
• SAS (side-angle-side)

In the diagram, EF is the bisector of ∠DFD′, and m∠DEF = m∠D′EF.

The triangle congruence criteria that can be used to prove that △DEF

and △D′EF are congruent is
