The moment due to all the components of the system of forces about a chosen point is equal to the moment due to the resultant about the same point is known as Varignon's theorem [[Image:Varignon parallelogram convex.svg|thumb|300px|Area(''EFGH'') = (1/2)Area(''ABCD'')]]

'''Varignon's theorem''' is a statement in [[Euclidean geometry]], that deals with the construction of a particular [[parallelogram]], the '''Varignon parallelogram''', from an arbitrary [[quadrilateral]] (quadrangle). It is named after [[Pierre Varignon]], who published it in 1731.
