A diagonal is a line segment that connects two non-adjacent vertices or corners of a shape. In geometry, diagonals are used to measure the size of figures such as polygons and right triangles.

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.

For a polygon, a diagonal is a line segment joining two non-consecutive vertices (not next to each other). One of the diagonals is shown for polygons A and B below.

A diagonal is a straight line that connects two non-adjacent corners (vertices) in a polygon. In simpler terms, it's a line that goes across a shape from one corner to another corner that isn't right next to it.
