What is a quadrangle? Do you mean Angel?
In all seriousness you can't. There are several areas just think about it. You need the diagonal length or some angles need to be right angles.
+118687 No the asker means a quadrilateral. (that is what I would call it anyway) Those are the langth of the sides.
When I was at school, many moons ago, our 'play areas' were bordered by 4 buildings.
These were referred to as quadrangles. (literally 4 anlges)
Each year of students had a different quadrangle in which we were meant to be.
I put 'play area' in inverted commas becasue we were not allowed to play.
It was an all girls school and we were expected to behave like 'ladies'
Some of you kids do not know how lucky you are. LOL
