Quadrangle

Audley Court was not an attractive locality. The narrow passage led us into a quadrangle paved with flags and lined by sordid dwellings.

What's the difference between a quadrangle and a quadrilateral?

Tom drew an irregular quadrangle.

I looked up from my desk and saw that suddenly there were big flakes twirling down into the quadrangle, settling on the carefully pruned shrubbery bordering the crosswalks, the three elms still holding many of their leaves, the still-green lawns.

The quadrangle surrounding the Far Common was never considered absolutely essential to the Devon School.
