*URGENT* I NEED HELP NOW! It about a two column proof! I have a chart too! PLEASE HELP ME! I don't know what the rest of them are, which is 3. WILL GIVE MEDAL @jim_thompson5910 @wio @Jhannybean @confluxepic @mathmate @DanJS @leonardo0430

Answer 1

Looking at these statements, you are given congruent triangles and are asked to prove that a quadrilateral is a parallelogram.

First thing, in any Geometry problem with a diagram, mark up the diagram. In this case I outlined the two congruent triangles in the hope that it would enable me to see how to get to the last step.

Answer 2

Recall that corresponding parts of congruent triangles are congruent. (CPCTC)
That will provide 6 pairs of congruent sides and angles.

The next step is to review how to prove that a quadrilateral is a parallelogram.
Consider reviewing that in your text.

Answer 3

I have marked some congruent parts here. See the attachment.

Answer 4

The blank for Step 2 has "Given" as its reason. I have just now realized that you did not state the Given in the problem statement.

So, would you look back in your text and post what information is given for the proof? Only then, can I continue. @kbhintze
