Applied Mechanics and Graphic Statics
According to Law of Triangle of Forces

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