planes can be thought of as two-dimensional lines.
Never Intersect? Yes
Intersect in One Line? Yes
Intersect in One Point? Yes
It is possible to draw three planes that are parallel to each other. Just as it is with parallel lines, parallel planes will never intersect. To better visualize this, think of the different floors of a skyscraper. If theses planes did intersect at some point, it would be a funny looking building.
Three planes can also intersect at one point. An example, of this can be seen below.
