Question

i need a little help i do not get this at all?


A student made the table below to show the steps to prove that DC is equal to EC...

A. Provide the missing statement and justification in the proof.
B. Using complete sentences, explain why the proof would not work without the missing step

Answer 1

What letters do DC and EC share?
Then plug in numbers for D, C, and E.. and then show DC = EC --> Plug your numbers into that equation (DC = EC)

Answer 2

what do you mean numbers?

Answer 3

Oh. I thought it was a simple proof.. this may take a little longer lol.

Answer 4

lol

Answer 5

im kinda struggling wiht the proofs and stuff like idk how to decide what goes next

Answer 6

It's been years since I have done proofs.. I can't remember exactly what is what. All I know is, if two lines (DC) and (EC) share a letter (C) they will be the same. Proofs are long and annoying. See if you can read up on a bunch of example proofs, eventually you will get there. Sorry.

Answer 7
