"Quadrangle" is a fancy way of saying "square" or "rectangle." It's often used to describe the shape of a building or an open space surrounded by buildings. For example, a college campus might have a quadrangle, which is a big square or rectangle of grassy area with buildings on all four sides. You can use the word "quadrangle" when you want to sound more formal, but it's not a word you would use in everyday conversation.
