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 |
