If a plane intersects a solid (a 3-dimensional object), then the region common to the plane and the solid is called a cro… See more

A cross section of a polyhedron is a polygon.
The conic sections – circles, ellipses, parabolas, and hyperbolas – are plane sections of a cone with the cutting planes at various different angles, as seen in the diagram at … See more

Cavalieri's principle states that solids with corresponding cross-sections of equal areas have equal volumes.
The cross-sectional area () of an object when viewed from a particular angle is the total area o… See more

In analogy with the cross-section of a solid, the cross-section of an n-dimensional body in an n-dimensional space is the non-empty intersection of the body with a hyperplane (an (n − 1)-dimensional subspace). This concept ha… See more

In geology, the structure of the interior of a planet is often illustrated using a diagram of a cross-section of the planet that passes through the planet's center, as in the cross-section of Earth at right.
Cross-secti… See more
