If any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon taken in order, then the forces are in equilibrium
if any number of forces acting at a point can be represented by the sides of a polygon taken in order, then the forces are in equilibrium
if any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon, then the forces are in equilibrium

If three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium
Three forces acting at a point can be represented by a triangle, each side being proportional to force
If three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
three forces acting at a point will be in equilibrium
