Question

In a plane, line b is perpendicular to line f, line f is perpendicular to line g, and line h is parallel to line f. Which of the following must be true?

a)f bisects h
b)g is parallel to f 
c)h bisects g 
d)b is parallel to h
 i think its either b or d

anonymous · Answer

b is perpendicular to f
f is perpendicular to g
implies
g is parellel to b


so , I'd go with c

jim_thompson5910 · Answer

line b is perpendicular to line f

|dw:1374355320479:dw|

jim_thompson5910 · Answer

line f is perpendicular to line g

|dw:1374355368393:dw|

jim_thompson5910 · Answer

line h is parallel to line f

|dw:1374355426156:dw|

jim_thompson5910 · Answer

we can't say anything definitive about any lines bisecting one another, so choice A and C are eliminated

jim_thompson5910 · Answer

b is perpendicular to f

so because f || h, we know that b is perpendicular to h

so b || h is NOT true, so choice D is eliminated

anonymous · Answer

no, it is not

jim_thompson5910 · Answer

that's not true either since g is perpendicular to f

jim_thompson5910 · Answer

if it was "g is perpendicular to f", then it would work

or if it was "g is parallel to b", then it would work

jim_thompson5910 · Answer

so there may be a typo

anonymous · Answer

but thats how its typed on the the test and its online so i directly copied and pasted it

jim_thompson5910 · Answer

hmm idk then, something to bring up with the teacher

hartnn · Answer

h bisects g must be true, the c) option

jim_thompson5910 · Answer

how do you know that hartnn?

anonymous · Answer

they are line ,not segment

anonymous · Answer

you drew them as segment

hartnn · Answer

oh.. in all her previous question, the word 'bisect' is taken as 'intersect', only then we get a correct choice/option 
whereas both mean different, i know

jim_thompson5910 · Answer

yes i know, but even if I extended the lines, there's no guarantee of any bisections

jim_thompson5910 · Answer

since you can easily shift things around

jim_thompson5910 · Answer

they should have used "intersect" since bisect means something completely different

not sure what they mean, but I'm guessing there's a typo

anonymous · Answer

since they are infinite in lenght , either side would have equal length

anonymous · Answer

i think it probably means intersect ill ask my teacher because thats how its typed in the computer

anonymous · Answer

but thanks !!!

jim_thompson5910 · Answer

np

hartnn · Answer

"intersect" in all your question will give you a correct option
'bisect' will never give you any option in all your Q
