Do 2 intersecting lines lie in 2 planes?
What's your idea about it. Just wondering before we discuss.
i belive yes, in my mind and how im seeing it play out in my brain it looks like there are two sperate planes
Im 16 trying to graduate this summer :)
Okay. I'll draw two intersecting lines and make a case for exactly one plane. Hold on.

LOL I made a fool of my self, thanks for helping! I was thinking of the totally wrong thing ;0

You did not make a fool of yourself. And, my argument may be incorrect.
No, cause two intersecting lines can never create 2 different planes
There has to be a 4th demension ;)
Here's my thinking: Line XY intersects line ZX at point X. Points X, Y, and Z are not on the same line. They are non-collinear points. By the axioms, three non-collinear points determine a unique plane. Therefore, exactly one plane contains the two intersecting lines.
What do you think? Now, if we ask if 3 intersecting planes lie in exactly one plane - well, that's a different story.
yeah i know haha, im using my arms and a piece of paper to figure it out :P
I use pencils and pens or whatever is handy. Visualization is so important in Geometry.
You have to agree haha
Hey what about this: Do a line and a point not on the line lie in exactly one plane?
