Question

Prove Theorem

Answer 1

oh gosh. i looked at it and i had a brain fart. i literally just learned this kind of proof this week. all i can say is to prove a parallelogram you need just one of these:

-opposite sides congruent
-opposite angles congruent
-consecutive angles are supplementary
-opposite sides are parallel

sorry. you can ask @Hero @jigglypuff314 or @kewlgeek555

Answer 2

@daniela.estrada u can prove BCEF is parallelogram using consecutively angles are supplementary

Answer 3

U will have to use a theorem that says if 2 parallel lines are cut by a transversal, then the interior angles on the same side of the transversal are supplementary

Answer 4

Becuz of that theorem^ u can say <FBC and < BCE are supplementary

Answer 5

so i can just put <FBC and <BCE are supplementary ?

Answer 6

@daniela.estrada

-------
Steps
-------

1. △ ABF ≅ △ DEC
2. Seg FB ≅ Seg CE
3. Seg FB || Seg EC
4. Quadrilateral BCEF is a parallelogram

Reason for Step 4:

If a quadrilateral has one pair of opposite sides both congruent and parallel, then the quadrilateral is a parallelogram.

Your task is to complete Reasons 1, 2, and 3.

Answer 7

lmfao, im slow i don't get it :c
