CONVEX POLYGON A polygon is a convex polygon if the line segments joining any two points inside it lies completely inside the polygon.

Convex polygon a polygon is a convex polygon if the line segment joining any two points inside it lies completely inside the polygon.

In a convex quadrilateral the line segment joining any two points in its interior lies completely in its interior.

A set of point represents convex polygon if

The number of diagonals of a convex polygon is 15 less than 4 times the number of its sides. The number of sides of the polygon be

r -sided polygons are formed by joining the vertices of an n -sided polygon.Find the number of polygons that can be formed,none of whose sides coincide with those of the n - sided polygon.

Convex polygon a polygon p_(1)p_(2)p_(3)...p_(n) is called a convex polygon if for each side of the polygon the line containing that side has all the other vertices of the polygon on the same side of it.

Find the number of diagonals in the convex polygon of n sides .

Polygons a polygon is a closed curve (figure)formed by the line segments such that: (i)no two line segments intersect except at their end -points.(ii)no two line segments with a common end points are coincident.
