Question

geometryyy

does this proof makes sense?

Answer 1

You're like... not quite there. The goal to prove these are parallel is to show that same-side interior angles are supplementary.

Answer 2

how do i do that?

Answer 3

Once you have shown that same-side interior angles are supplementary, you can appeal to the converse of the same-side interior angles postulate to say that the lines are parallel.

Answer 4

so do i have them in disorder or my reasons are just wrong?

Answer 5

Your first few steps are right. After you've shown that 2+5=180, notice that 2=3, and state why that is so.

Answer 6

so after 2+5=180 i should put 2=3 vertical angle theorem?

Answer 7

Cool. Now it's your turn. What does that let us say next?

Answer 8

3+5=180?

Answer 9

And why can you say that?

Answer 10

because they are supplementary

Answer 11

That's a restatement of the same thing. It's not a reason for saying it.

Answer 12

Nope. Make sure your reasons actually make sense.

Answer 13

which one is wrong?

Answer 14

For example, your last statement is Line L || Line M because of substitution. Substitution of what? Into what? That's just a guess because it doesn't make any sense.

Answer 15

looks fine to me,

Answer 16

Don't listen to him. It's definitely incorrect.

Answer 17

makes perfect logical sense
the subsitution is \[\angle 2=\angle 3\]

Answer 18

-_- nope.

Answer 19

smoothmath so the last one is wrong?

Answer 20

what are the options for the reasons?

Answer 21

I'd rather that instead of asking me which ones are wrong...
just go through your proof step by step and try to see if you have a clear step by step logic.

Answer 22

unklerhaukus, the point is to move the statements around until you organize them in order and logical sense

Answer 23

im so confused -.-'

Answer 24

you have 4,5 the wrong way around
