prove that this is right :
The area of a general irregular quadrilateral is equal to half the product of the diagonals and the sine of the angle between them.

there is a rule to get the area of the square or rectangle or anything with four ...
which is : half the product of the digonal X sin !
in the square sin 90 = 1
so its : half the product of the diognal
can anyone tell me where did they bring that rule from ?
