Given:

Prove: Same-side interior angles are supplementary

Answer 1

What is a paragraph proof?

Answer 2

idk honestly

Answer 3

I never heard of it before, let me look around....

Answer 4

alright thank u

Answer 5

Answer 6

Seems like the proof you want , don't know whether it counts a "paragraph" proof...

Answer 7

Ah, OK I found out the difference between the proof in the link I gave you and a paragraph proof.

Answer 8

i have no eartly idea im horrible at this stuff

Answer 9

OK, so you basically just have to translate the 2 column proof (which is a valid proof) into something more like plain English but so that it is still convincing.....

Answer 10

i dont know what to write :/

Answer 11

You will have to try and translate the 2 column proof.
If I do it, it will be very obvious that you didn't do it and anyway you should have a go.
First you can try to understand the 2 column proof, if you can do that it will be much easier to write the paragraph proof...

Answer 12

So like the first line just says "OK, we have a couple parallel lines and a transversal"

Answer 13

okay

Answer 14

Then personally I wouldn't bother with 2 and 3, just go straight to 4 and say "Clearly such and such angle is 180 degrees because it's on a straight line"

Answer 15

Anyway you try and show me your effort tomorrow, I am off to bed....:-)
