In geometry, a diagonal is a line segment joining two vertices of a polygon or polyhedron, when those vertices are not on the same edge. Informally, any sloping line is called diagonal.

A line segment joining one corner to another but is not an edge is called a diagonal. In other words, a diagonal is a line that connects the opposite vertices of a polygon.
