What is a diagonal line in a shape? In geometry, a diagonal line is a straight line segment that joins two corners of a polygon, but is not an edge. It goes through the middle of the shape. It …

A diagonal line is a line segment that connects two non-adjacent vertices of a shape. It is usually longer than other lines in the shape, and it usually follows a curved path.

A diagonal line is a straight line connecting two corners (or vertices) of a polygon that are not next to each other. The polygon in question must have 4 or more vertices.
