Lami's theorem states that

Three coplanar forces acting at a point will be in equilibrium if each force is inversely proportional to the sine of the angle between the other two

If three forces acting on a point can be represented in magnitude and direction by the sides of a triangle, the point will be in the state of equilibrium

Three coplanar forces acting at a point will be in equilibrium, if each force is proportional to the sine of the angle between the other two

Three forces acting at a point are always in equilibrium
