three lines that intersect at the same point must all be in the same plane? true or false? tell me bout planes

Question

thanks

Answer 1

FALSE. Look at the corner of your room, where the walls meet the ceiling. Three lines, 3 different planes (2 walls and ceiling).

Answer 2

false. A plane contains only points on its surface. Like a flat piece of paper.

Ever play jacks with a ball and one-zies, two-zies etc. A jack like that is 3 lines intersecting. If the three lines were on the same plane , the jack would be flat, but it's not. Flat, like as if a truck drove over it.

Answer 3

Not necessarily because the lines themselves could be intersections of two planes and the point is the intersection of all three planes.

Ah, geometry. Brings back my good old school days...
