Geometry is a branch of mathematics that pertains the the location and attributes of a point, line, shape or solid. Geometry is used to find volume, area, and other properties of shapes. Because of these properties, it is a very practical mathematical tool for use in industries such as farming, construction, engineering, and even astronomy.
Because of the practicality of determining volumes and areas, geometry was highly adopted by early cultures. One of the earliest pioneers of geometry was Euclid. Euclidean geometry. Euclid's work in the 3rd century B.C. was followed and utilized for centuries. In addition to Euclid, Archimedes added to the study of geometry by developing new techniques for calculating area and volume. And, if you've every studied geometry, I'm sure you've heard of Pythagoras and the Pythagorean Theorem that explains the calculation of the hypotenuse of a right-triangle.
Although many new students are familiar with the term "volume", it may not be the geometric version. While volume is referred to in terms of sound, it explains a slightly different aspect in relation to mathematics. Volume is a measure of quantity in a three-dimensional space. A simple example would be the volume of a 1 gallon milk container. In a 1 gallon milk container, there is 1 gallon of space within the container. That is what volume pertains to in geometry. The space in a containing 3-D shape.
Area is the the two-dimensional version of space within a container. Unlike volume, area pertains to only 2-D shapes. An example would be the area within a flat shape like a basketball court. A basketball court is a flat floor, it has only length and width. When you multiply the length by the width, you find the total area in square units.
Because geometry is a very practical mathematical tool, it is important to have a strong grasp of geometric calculations. Knowing the principles behind calculating the hypotenuse of a triangle, or finding the volume of a cone, can come in handy.
