If they meet at right angles
...parallel to each other.
A line.
A perpendicular intersection of two planes is represented by a line that is orthogonal to both planes. This line acts as the common line of intersection where the two planes meet at a right angle (90 degrees). This geometric configuration is often visualized in three-dimensional space, where the planes can be thought of as sheets extending infinitely in their respective dimensions.
Parallel, Perpendicular, and Planes.
The solid enclosed by this surface and by two planes perpendicular to the axis is also called a cylinder.

...parallel to each other.
A line.
No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
Parallel, Perpendicular, and Planes.
No. Perpendicular is an adjective. It cannot be a preposition.

Coordinate planes
no planes are not perpendicular to each other because for air resistance the planes are designed in a such way that air is avoided to back side and they are inclined to each other.
Yes
Two planes are parallel if the perpendicular distance between them remains constant. This is not a British definition but a mathematical definition and so is valid everywhere.
