Q:

# How is geometry used in real life?

A:

Many occupations including architects, designers, farmers, construction workers and medical professionals incorporate geometric concepts into their work. Even individuals outside of these professions use geometry when measuring walls, calculating how much paint is needed for a project or determining whether new furniture can fit through a door. Geometry is a practical guide for measuring lengths, areas and volumes.

Geometry focuses on the properties of space and figures. It simplifies calculating area, perimeter and volume. It also helps people understand objects spatially, conceptualizing how the position, size and shape of a space relate to the things inside that space. For instance, if someone wants to buy a new dishwasher, knowing how that appliance fits spatially with the other cabinets, furniture and appliances in the room helps to determine what type or size of dishwasher to purchase.

Designers and architects deal with three-dimensional figures constantly. Geometry helps determine how a building, something composed entirely of three-dimensional shapes, is constructed. Medical professionals make use of geometric imaging with technology such as CT scans and MRIs.

Mapping also requires a solid foundation in geometry. Occupations that involve surveying, navigation and astronomy use maps to illustrate where things are located. Looking at maps requires geometry as well. Maps spatially display where a destination is, and through measurement, help determine how long it takes to get there.

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.

Euclid of Alexandria is called the Father of Geometry. He received his education at Plato's Academy in Greece and moved to Egypt to teach. He taught during the reign of Ptolemy I Soter, the first Macedonian ruler. Euclidian geometry has been taught in schools for a long time.

One common example of perpendicular lines in real life is the point where two city roads intersect. When one road crosses another, the two streets join at right angles to each other and form a cross-type pattern. Perpendicular lines form 90-degree angles, or right angles, to each other on a two-dimensional plane.
