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

If the forces acting on a particle be represented in magnitude and direction by the two sides of a triangle taken in order, their resultant will be represented in magnitude and direction by the third

Three forces acting at a point, can be rep-resented by the sides of a triangle, each side being in proportion to the force

Three forces acting along the sides of a triangle are always in equilibrium
