In a plane, two lines perpendicular to the same line are perpendicular to each other.
Classify the statement below as always, sometimes or never true:
Hmm, let the line be |dw:1404490437043:dw| The 2 lines perpendicular to that line would look like |dw:1404490461121:dw| Are those 2 lines perpendicular?
yes
so is that always true
|dw:1404490549043:dw| Those lines are perpendicular?
or sometimes
yep
|dw:1404490593297:dw| I'll just leave this graphic up and see if you still agree
is it possible for you to give me th answer because I have more questions for you
like
Classify the statement below as always, sometimes or never true: A line which intersests one of two parallel lines intersects the other also.
and
Classify the statement below as always, sometimes or never true: Two planes parallel to the same line are parallel to each other.
plleaase help me
i dont agree anymore i see the fault
When you deal with this kind of problem, choose you own answer, then: If you find at least one case where it is true, then it's either always true or sometimes true. If you find at least one case where it is false, then it is NOT always true. If you find one case of each (true and not true), then it is sometimes true. You'll have to find other ways to decide on the other cases.
