If these two lines are in the same plane, and they are not the same line, what can you state about them?

Two non-parallel lines intersect at only 1 point.

Re: Help line

plz rationalise denominator


5/3+(root)5-2(root)2


There are always 2 ways to code and only the third one is correct.
And this happens with MATHEMATICS also.

Re: Help line

hi coolcoder

Welcome to the forum.

Please don't post your problem in someone's else's thread.  This will be confusing for that OP.

As it stands your problem doesn't make sense anyway.  There is no fraction so "rationalise denominator" is not possible.

This is how you can display a fraction:

[math]\frac{numerator}{denominator}[/math]

will make this:

and square roots like this:

[math]\sqrt{5}[/math]

So start a new thread and try again.

Thanks, smile

Re: Help line

Hi Cooclcoder;

Bob is right. Plzz post in a new topic, if your problem is not related to it. You will find it here:

As for your answer, I think you ask this:

And you asked :

plz rationalise denominator

The denominator is already rationalized. The denominator for the fraction is 3 which is a ratiional no. so, your fraction is also rationalized. Hope you get the answer.

Re: Help line

hi Zeeshan 01

I thought your original question had been answered.  If it hasn't please make clear: is this a question in 2 dimensions or 3?  The answers is different in these two cases.

Now I am clearly telling you, listen to me. You too are confused and are confusing me too.

Parallel lines are those lines which never meet (or you can say meet at infinity) when extended on both sides.

Non-Parallel lines (also called intersecting lines) are those lines which meet at only 1 point, when extended on both sides.

Re: Help line

hi Zeeshan 01

I hope this diagram will help you.

UPpbmgM.gif

If the lines are AB and CD and they are both in the same (2 dimensional) plane, then they must cross (when not parallel).  When parallel the distance between them is constant but if not parallel then the distance between will vary and can be zero.  This means they cross.  In this case the answer is 1 point.

In 3 dimensions it is possible for the lines to be 'skew'.  Skew lines are not parallel but do not cross.  In the diagram AB and EF are a pair of skew lines.  AB is confined to the top plane and EF cuts that plane once at F, so these lines never cross.  Number of points is then zero.

If the 'two' lines are, in fact, just a single line then they 'cross' everywhere, so they would have an infinity of crossing points.  But two lines that are the same line are considered to be parallel, so infinity will never be an answer.
