Many high school students view geometry as the study of shapes. This includes anything from simple triangles to complex icosahedrons. Geometry studies the unique properties of different shapes and figures.

Many high school students may not be fond of it, but geometry has lots of serious real-world applications. Determining volumes, areas, and perimeters are very useful in the realms of manufacturing, real estate, and construction.

Really? Real estate? How can geometry be used in selling houses? Well, it has to do with measuring land area. Real estate is concerned quite much with land, so geometric formulas can help surveyors determine the area and perimeter of a patch of land. That way, the boundaries of a lot can be set, and trespassing can be prevented. Realtors can then more easily sell patches of land because they know the exact area as well as the precise boundaries of the land.

In the world of manufacturing, the use of geometry is more obvious. Take a milk factory as an example. Each milk carton or bottle must have a specific volume so that when they go through the milk machine, the milk won’t overfill the cartons or bottles. Those volumes must be precisely under control, and getting the volume of the containers requires a lot of geometry.

Construction also benefits much from the concepts of geometry. When building a house, for example, geometry drives a lot of the work: what length of planks to use, the thickness of the wood, the angles of the roofing, and many more. The way an architect designs the shape of the house is also governed by geometry. From exterior to interior, a house cannot be built without a solid knowledge of the principles of geometry.

Even designing furniture involves a lot of geometry. Countertops, tables, chairs, and couches could not have been made without it. Geometry is all around the home, and all around our modern world too.
