Polygon-convex and concave polygons

Question

Illustrate the term polygon? Also differentiate between convex and concave polygons?

Answer 1

The polygon is any closed continues series of line segments that is, a polyline whose last node point is similar as that of its first or initial node point. Line segments form the sides of polygon and their intersecting points from the vertices of polygon.

When the line joining any two points in polygon lies completely within the polygon then, they are termed as the convex polygons. When the line joining any two points in polygon lays exterior the polygon then, they are termed as concave polygons.
