Hello! I have to write a 2 column proof.
Given: ABDF is a parallelogram.
Prove: Triangle CBD is similar to Triangle DEF.
All I have so far is the black annotated markings on parallelogram ABDF, which is what I know of parallelograms. I don't know how to prove them similar yet. And all I have so far for the proof:
Statements | Reasons |
ABDF is a parallelogram | given |
DB parallel to FA, DF parallel to BA | definition of parallelogram |
Angle DBF = Angle DFA, Angle BDF = Angle BAF | Opposite angles congruent |
