00:00

Thank you We sneak in and here's your shmoop du

00:05

jour brought to you by parallel lines They're just one

00:09

old lady away from being a parallelogram Which of the

00:14

following statements would be sufficient to show that lines and

00:17

see below are parallel and hear the potential answers you

00:21

understand her already know numbers or equations to get in

00:26

the way here just plain and simple What are the

00:28

properties of parallel lines And how could we prove that

00:31

a and c belonging that club Well we've got this

00:35

trans verceles thing here line be that cuts through both

00:38

of them That guy has to play into things somehow

00:41

let's look over the answer choice and see what our

00:43

options are Option b can't possibly be right It starts

00:46

by assuming that is perpendicular to see and if that

00:49

were true then they couldn't possibly be parallel So is

00:52

that a same deal for choice D waken nix that

00:56

one two what about answers See well a is perpendicular

00:59

to be yeah it's a start but just knowing that

01:02

is perpendicular to be doesn't tell us anything about a

01:05

relationship to see oh yeah our answer has to be

01:08

the first one is perpendicular to b and b is

01:11

perpendicular to see if that were true We'd have a

01:14

pair of alternating interior right angles right chair in here

01:18

And if these two angles air congratulate then by rule

01:21

lines a and c must be parallel So answer it

01:25

is Our parallelogram would be so proud of us like 00:01:30.076 --> [endTime] some candy
