diagonal
A line segment joining two adjacent vertices of a polygon is called an edge or a side. A line segment joining two non-adjacent vertices is called a diagonal.
it is called a diagonal.
A polygon need not have any lines of symmetry. The maximum number of lines of symmetry is attained if the polygon is regular; and this is the number of sides (or vertices) of the polygon. If a regular polygon has an even number of sides, then the lines of symmetry are those joining opposite vertices, and those joining the mid-points of opposite sides. If the polygon has an odd number of sides/vertices, the lines of symmetry are those joining each vertex to the mid-point of the opposite side.
concave
diagonal
The points where the line segments that form a polygon meet (i.e., the corners) are called the vertices of the polygon. The singular form is vertex.

A line segment in a polygon connecting any two nonconsecutive vertices is called a diagonal.
