Cross Section

The cross section of a solid is a plane figure obtained by the intersection of that solid with a plane.

Cross section is a high school-level concept that would be first encountered in a geometry course covering solid geometry.

Prerequisites

A plane is a two-dimensional surface defined by linear equations.
