When two planes intersect (such as the edge of a rectangular box), the intersection is a line (not a point).
When two planes do not intersect(such a the top and bottom faces of a rectangular box), then they don't intersect at exactly one point.
A pair of intersecting planes ______ intersect in exactly one point?
A- always
B- sometimes
C- never
D- not enough information
I think A- always, but I do not know for sure.
