# Calculation of convex polygon related online formula

Category:

### App description Convex polygon refers to that if one of the edges of a polygon is infinitely extended to two sides to form a straight line, and other sides are on the same side of the line, then this polygon is called a convex polygon, and its internal angles should not be favorable angles.

Convex polygon can be defined as follows:

A polygon in which no interior angle is a dominant angle.

If one of the edges of a polygon extends infinitely to two sides to form a straight line, and all other sides are on the same side of the line, then the polygon is called a convex polygon. A convex polygon is a simple polygon with a convex set inside. The following properties of a simple polygon are equivalent to its convexity:

1.All internal angles are less than or equal to 180 degrees.

2.The line segment between any two vertices is located inside or on the edge of the polygon.

3.The line between any two points in a polygon is inside or on the edge of the polygon.
