Q:

How is geometry used in astronomy?

A:

According to teach-nology.com, geometry is used in astronomy to determine the properties of stars and other objects in space. It is developed to be a practical guide in measuring the velocity, area, volume and length of heavenly bodies. Astronomy is the study of these objects, and geometry assists in figuring out their scope and placement in the firmament.

According to Encyclopaedia Britannica, Greek astronomers used geometry by supposing that the planets, the moon and the sun moved around a stationary earth in a set of circles. To achieve this, they calculated the speed of these circles from points of observed motion.

Geometry in nature is found practically everywhere, states Wonder Whizkids, from the proportions of the human body to the shape of a shell. In the early days, the focus of geometry seemed to be on solids and shapes, before it slowly moved to the properties of objects and the relationship between shapes and solids.

Today, geometry is much more about reasoning and analysis. Geometry has a lot of practical uses in real life, as well, says teach-nology.com. For example, it can be a huge factor in how a person goes about his daily business. For instance, a person turning while driving is unconsciously using geometry to calculate the radius of the turn. It is also much used in industry, such as when planning construction projects.

    What are the uses of a laser pointer in astronomy?

    A:

    Laser pointers are used by astronomers to point to notable locations in the sky. They are popular tools for public stargazing with groups because they can easily direct the attention of the whole group to a particular constellation or celestial object. Laser pointers are also used as finders, tools that locate celestial objects and help an astronomer point the telescope toward the correct location for closer observation.

    How is geometry used in everyday life?

    A:

    Geometry is used in everyday life for building and construction, home decorating, outdoor projects and professional work. The geometric formulas for area and perimeter are often used to accomplish projects that require room and object measurements. For squares and rectangles, the area = base x height and the perimeter = base x 2 + height x 2.
