Talk:Area of Quadrilateral with Given Sides is Greatest when Quadrilateral is Cyclic

Is this result ever quoted as being "a corollary to Bretschneider's Formula"? I haven't studied the literature.

Anybody got any problems if I start calling it "Bretschneider's Corollary" or something like that? He hasn't got much to his name, and otherwise this title is big and unwieldy. --prime mover (talk) 13:02, 20 December 2022 (UTC)
