Closed Captioned Video: Geometry Applications: Quadrilaterals
In this program we explore the properties of quadrilaterals. We do this in the context of two realworld applications. In the first, we explore the architecture of Frank Lloyd Wright as an application of squares and rectangles; in particular, we look at his Fallingwater house.

The Puerta de Europa towers in Madrid bring parallelograms front and center. These tilted towers, looking like modernday towers of Pisa seem to defy gravity, but rely on the stability brought about by its quadrilateral structure.
