Two points define a line, but if there are two lines in a plane, and if they intersect somewhere, they “define” a single point. If there are two planes in space, and they intersect, what do they define? (Look at the walls of your room, where they meet. Imagine if there were no floor or ceiling, and the walls went up and down and side to side forever, what would the corner where they meet look like?)

A. a ray
B. a line
C.a point
D. a plane
E. a partridge
F. a pear tree

line cross line = point

plane cross plane = line

space cross space = plane

hyper cross hyper = space

i still dont understand

Well its safe to cross off the last 2...

It's not a line, it's not a ray, and it can't be a plane. So you're stuck with a point.
