Part B Is it possible that you could use other transformations to prove the shapes in part A are congruent?

∠cbe and ∠deb are same-side interior angles.

i took the test

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
