Okay. I'll draw two intersecting lines and make a case for exactly one plane. Hold on.

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

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 noncollinear points. By the axioms, three noncollinear 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.

I use pencils and pens or whatever is handy. Visualization is so important in Geometry.

Hey what about this: Do a line and a point not on the line lie in exactly one plane?
