The Law of Polygon of Forces states that

• if a polygen representing the forces acting at point in a body is closed, the forces are in equilibrium
• if forces acting on a point can be represented in magnitde and direction by the sides of a polygon taken in order, then the resultant of the forces will be represented in magnitude and direction by the closing side of the polygon
• if forces acting on a point can be represented of a polygon taken in order, their sides of a polygon taken in order, their resultant will be represented in magnitude and direction by the closing side of the polygon, taken in opposite order
• if forces acting on a point can be represented in magnitude and direction by the sides of a polygon in order, the forces are in equilibrium.
