Definition
Let $C$ be a double napped right circular cone whose base is $B$.
Let $D$ be a plane which intersects $C$.
Let $K$ be the conic section formed by the intersection of $C$ with $D$.
The plane $D$ is known as the slicing plane of $C$ for $K$.
Also known as
The slicing plane is also known as the plane of section.
