Question

I need more help again will medal and fan!!!

Write a paragraph proof of theorem 3-8: In a plane, if two lines are perpendicular to the same line, then they are parallel to each other.

Answer 1

Please help @DanJS

Answer 2

@vera_ewing

Answer 3

can you help @jackthegreatest

Answer 4

hey @cool4u2001
im not sure i can help, but i can try
sorry i just left off on ur problem

Answer 5

That fine, If you can try you know more than me. lol I do not get it at all!!

Answer 6

ok

Answer 7

r u given any angles degrees?

Answer 8

i dont remember many theorems lol, its been a while since i did these type of problems

Answer 9

No, what i am given is that r is perpendicular to s and t is perpendicular to s. I'm trying to prove that r is parallel to t

Answer 10

oh wait if r and t are perpendicular to the same line then their parallel, Do you know what this theorems called?

Answer 11

I think it would be something like alternate interior angles theorem

Answer 12

im thinking its the converse of something

Answer 13

I found a site; would any of these match it?

Answer 14

wait a min, that means all of the angles r 90 degrees...

Answer 15

It alternative exterior angles i think

Answer 16

haha i k the theorem, i found it on this website: http://web.cerritos.edu/dford/SitePages/Math_70_F13/PostulatesandTheorems.pdf

Answer 17

If two coplanar lines are perpendicular to a
third line, then they are parallel to each
other

Answer 18

idk wats its called...

Answer 19

ahhh i know wat it is now, i think
converse of the parallel lines theorem

Answer 20

If two lines are cut by a
transversal to form
pairs of congruent corresponding angles,
congruent alternate interior angles, or
congruent
alternate exterior angles, then the lines are
parallel.
