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. Learn the …

A diagonal is a line segment connecting the opposite vertices or the non-adjacent vertices of a polygon. Learn about the diagonals of polygons, examples, & more.

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.

Jul 24, 2025 · Diagonal of any polygon is the line segment joining the vertices of the polygon that are not on the same edge. The length of the polygon depends on the type of polygon.

The meaning of DIAGONAL is joining two vertices of a rectilinear figure that are nonadjacent or two vertices of a polyhedral figure that are not in the same face.

A diagonal is a line segment that connects two non-adjacent vertices (or corners) of a polygon. In simpler terms, it joins two corners that aren't already connected by an edge of the shape.
