If multiple forces acting at a single point can be depicted by the sides of a polygon.If several forces applied at a point are represented by the sides of a polygon in terms of their magnitude and direction, then the forces are balanced.When a polygon formed by forces acting at a point is complete, the forces are balanced.If any number of forces acting at a point can be represented in both magnitude and direction by the sides of a polygon taken sequentially, then the forces are in equilibrium.None of the above statements are true.

Explanation

The law of the polygon of forces states that if multiple forces acting at a point can be represented in both magnitude and direction by the sides of a polygon taken in sequence, then these forces are in equilibrium. This means the polygon formed by these force vectors closes, indicating a balanced system.
