A STRAIGHT LINE PARALLEL TO THE PLANE. PARALLEL PLANES.

Abstract

Annotasiya. Will perpendicularly of the planet to the straight line. Mutually perpendicular planet. The straight line between the two and determine the means and planet planet. A straight line which is perpendicular to the plane passing through you at any given second, this plane is mutual perpendicular. The angle between the straight line and the plane, as this is the angle between a straight line of a given projective plane I ortogonal. The angle between the two-plane angle between two straight lines that are perpendicular to the line of their intersection with a linear measure.
