In real life, there are many different applications of geometry including everyday uses such as the "stop sign," which is an octagon shape. The shape, volume, location, surface area and various other physical properties are central to the objects around people.
Another example of geometry used in everyday life would be in providing a home for fish. A fish tank needs to be filled carefully so that it does not overflow and so that it is at the right capacity to sustain the fish. To determine the appropriate amount of water to be used, a person must use basic geometry.
Yet another example of geometry used in everyday life would be wrapping a gift. When a person is wrapping a gift, they must determine the appropriate amount of gift wrapping to use in order to wrap the gift in the best possible way. This requires a use of geometry to determine the best shape and size.
Geometry is also used in a more technical sense within various job disciplines such as design and manufacturing, medicine and biology, robotics, graphics and visualization, information systems and physical sciences. Architecture is one of the applications of geometry that is crucial because architects are responsible for building sound structures and they must use geometric components to do so.
