Question

I need help with this Embedded Assessment really badly, because I don't know how to figure it out. I know the information, but don't know what to put down. Medal will be rewarded! :D

Answer 1

idk this word proof things, but I can proof two triangles to be congruent.
DE = BE (Given)
AB || CD (Given)
angle ABD = angle BDC (alternate interior angles are congruent)
angle BAC = angle ACD (alternate interior angles are congruent)
triangle EAB = triangle ECD (SAA postulate)

Answer 2

Anything could work

Answer 3

then to prove number 5 of whatever
AE = EC (idk name, congruent triangles have congruent corresponding sides)
therefore by definition of bisecting and midpoint E is midpoint of AC

Answer 4

I could do the 2 column proof if I have the flow chart

Answer 5

I never learned flow chart, sorry :/

Answer 6

do you know a 2 column proof

Answer 7

would this work?
DE = BE (Given)
AB || CD (Given)
angle ABD = angle BDC (alternate interior angles are congruent)
angle BAC = angle ACD (alternate interior angles are congruent)
triangle EAB = triangle ECD (SAA postulate)

Answer 8

hmmm... normally I've never seen two givens next to each other

Answer 9

I haven't done geometry in many years, so it might be a bit off ;)

Answer 10

well it's a good job! :D

Answer 11

I did the best I could and that's all I know...
Good Luck! :)

Answer 12

thanks for the help! :D
