Wildlife Refuge	Description In this module students use their geometry and algebra skills to analyze a wildlife refuge in Nevada. Calculating the area, perimeter, and the ratio of the two allows students to analyze different configurations for a refuge. Specifically, they look at ways of designing a wild horse refuge, using the concepts they have learned.

Closed Captioned Video: Geometry Applications--Antiprisms	Description In this video students learn the basics of antiprisms, in the context of New York’s Freedom Tower, which has an antiprism design. They learn the properties of antiprisms, with the focus on those with a square base. A Video Transcript is available for this tutorial.	Rectangular Prisms
Closed Captioned Video: Geometry Applications--Rectangular Prisms	Description In this video students learn the basics of rectangular prisms, in the context of a New York residential tower: 432 Park Avenue. They learn the properties of rectangular prisms, with and without square bases, and the architectural requirements that influence the use of both types of rectangular prisms.	Rectangular Prisms
Closed Captioned Video: Geometry Applications--Triangular Prisms	Description In this video students study a real-world application of triangular prisms: The Flat Iron Building in New York City. This building is an ideal example of a real-world prism and also provides a tie-in to right triangle geometry.	Triangular Prisms
Closed Captioned Video: Geometry Applications--What Are Prisms?	Description In this video students learn the basics of prisms and anti prisms. They learn the properties of triangular prisms, rectangular prisms, triangular antiprisms, and rectangular antiprisms. A Video Transcript is available for this tutorial. Note: The download is Media4Math's guide to closed captioned videos.	Rectangular Prisms, Triangular Prisms
Closed Captioned Video: Geometry Applications: 3D Geometry	Description In this program we explore the properties of three-dimensional figures. We do this in the context of two real-world applications. In the first, we look at the three-dimensional structure of Mayan pyramids. These stair-step structures provide a unique opportunity to also explore sequences and series.	3-Dimensional Figures
Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 1: Introduction.	Description We visit ancient Greece to learn about the Platonic Solids. This provides an introduction to the more general topic of three-dimensional figures. This video includes a video transcript:	3-Dimensional Figures
Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 2: Pyramids	Description Rectangular Prisms. Mayan pyramids are essentially stacks of rectangular prisms. The volume of each successive level is a percentage decrease of its lower neighbor. This introduces the notion of a geometric sequence and series, including an infinite series. A Video Transcript is available for this tutorial.	3-Dimensional Figures, Pyramids
Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 3: Cylinders	Description The Shanghai Tower in China is a stack of cylindrical shapes, where each successive layer is a percentage decrease of its lower neighbor. As with the previous section, this introduces the notion of a geometric sequence and series. A Video Transcript is available for this tutorial.	3-Dimensional Figures, Cylinders
Closed Captioned Video: Geometry Applications: Quadrilaterals	Description In this program we explore the properties of quadrilaterals. We do this in the context of two real-world 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.	Definition of a Quadrilateral, Applications of Quadrilaterals
Closed Captioned Video: Geometry Applications: Quadrilaterals, Segment 1: Introduction	Description Stonehenge is best known as a circular structure. But it’s the post and lintel construction used that is noteworthy, and this type of construction involves quadrilateral shapes.	Definition of a Quadrilateral, Applications of Quadrilaterals
Closed Captioned Video: Geometry Applications: Quadrilaterals, Segment 2: Squares and Rectangles	Description Frank Lloyd Wright’s architectural masterpiece Falling Water is also a stunning assembly of quadrilateral shapes. Some of the rectangular forms in this building seem to defy gravity, as we explore the properties of squares and rectangles that allowed Frank Lloyd Wright to push the envelope of design and structure.	Definition of a Quadrilateral, Applications of Quadrilaterals
Closed Captioned Video: Geometry Applications: Quadrilaterals, Segment 3: Parallelograms and Trapezoids	Description The Puerta de Europa towers in Madrid bring parallelograms front and center. These tilted towers, looking like modern-day towers of Pisa seem to defy gravity, but rely on the stability brought about by its quadrilateral structure. The underlying parallelogram and trapezoidal designs are explored and analyzed.	Definition of a Quadrilateral, Applications of Quadrilaterals
