The number of lines making equal angles with Co-ordinate axes is ?

AI Thread Summary
The discussion centers on the number of lines that can make equal angles with the coordinate axes. One participant suggests there are four lines (or eight rays), while others argue that the answer depends on specific conditions not clearly stated. Key considerations include whether the angles are measured from positive or negative directions and whether the context is two or three dimensions. The lack of clarity in the original question leads to differing opinions on the correct answer. Ultimately, the resolution hinges on defining the conditions for the angles in question.

Hello mr B, welcome to PF :smile: !

Please explain it is a bit short. Explain what, precisely ?

Have you made any attempt at a solution yourself? What do you think it might be and why?
 
I think it's 4 lines (8 rays) but there are some who are opposing me..What is the right answer?

There is not a "right" answer, because you have not fully stated the conditions to be met. Personally, I agree w/ you but, again, it depends on the specified conditions (which you have not stated). For example, are we talking about angles from the positive x, y, and z directions or is it OK that the angle be from the negative directions?

Also, are we talking about coordinate axes in two or three dimensions?

I don't think he could have possibly come up with 4 lines if it were not 3D, so I think that's inherent in his post.
