Definition:Degenerate Case
From ProofWiki
Definition
A degenerate case is a specific manifestation of a particular type of object being included in another, usually simpler, type of object.
Example
A pair of intersecting lines are a degenerate case of a conic section. Such an object is formed by the intersection of a plane with a double napped cone such that the plane passes through the apex of the cone.
