A diagonal is a straight line connecting the opposite corners of a polygon through its vertex. To learn about diagonals, we must first know that:
It (diagonal) is a line segment.
Polygons are plane figures having at least three sides and angles and usually, it is used to identify figures having five or more sides and angles.
Vertex is a corner of the shape.
So, diagonal is a line segment connecting two non-adjacent vertices of a polygon. It joins the vertices of a polygon excluding the edges of the figure. The following shapes have a diagonal drawn on them
