1. if a polygen representing the forces acting at point in a body is closed, the forces are in equilibrium
2.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 th
3. 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
4.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.
