Prove either that there are infinitely or finitely many(if finitely many, specify how many) distinct quadrilaterals with distinct ,real, nonzero, side lengths w,x,y,z. I have a proof that there are infinitely many, but I am not sure how rigorous/ valid it is.
Note:Some people may think that there is only one such quadrilateral. This is what I thought originally. But then why do we need 4 sides and two angles to find the area of an arbitrary quadrilateral?

What are distinct critery , because if you have the quadrilateral sides ie. ( 1 , 2 ,3 ,4 ) angles any , and you multiply each side by a real number you will get infinites quadrilaterals.

No, the sides have to be kept the same. You cannot multiply each side by a factor.

OK . then you can change angles keeping condition A+B+C+D = 360ª
ie : if you change any angle betwin 40º and 50º you can get infinite angles of 40 + 10/ R with R a Real number as big as you want , and other angles change acording of that.
