A : three forces acting at a point are always in equilibrium
B : 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
C : three coplaner forces acting at a point will be in equilibrium, if each force is proportional to the sine of the angle between the other two
