The Meaning of Geometry
Geometry is one of the oldest branches of mathematics that examines spatial qualities relating to distance, shape, size, and figures. Its origins are attributed to the Ancient Greek word “geometry” (Greek for “earth or land measurement”) and “metric” (Greek for “measure”).

The word geometry can also be used as an umbrella term for all mathematical topics pertaining to points, lines, curves, angles, surfaces and solids. It is an essential part of a student’s education as it helps them to bring together both sides of their brain – left and right – and develop logical reasoning, deductive thinking, analytical thinking and problem-solving abilities.
In a way, all aspects of life are geometrical in nature. From the tires on your car to the glass of juice you drink every day, everything has some sort of geometric shape or pattern. Architects and builders use this knowledge to build sturdy structures.
Art is another example of how geometry can be found in everyday life. From painting to drawing different designs and even planning how a robot arm can grasp a shape, these activities require the understanding of various shapes, measurements and patterns.
Technology and video games are other examples where geometry plays a crucial role. From vector graphics to the terrain in games, all these are geometrical in nature.
It is a powerful tool for designing and calculations, which are very important for many technological and scientific fields. This is why a student’s education must include the study of geometry as it helps them to excel in their chosen career path.
Plane Geometry – This is the basic form of geometry that deals with flat shapes like circles and triangles. In addition, students can also learn to work with spherical geometry.
Straight Line – In planar geometry, a straight line is a combination of infinite points. It extends in both directions without an endpoint. In order to find the direction of a point, one must know the x-value and y-value of that point.
Ray – In planar geometry, a ray is a figure formed by two lines that share a common endpoint, called the vertex of an angle.
Acute Angle – In planar geometry, an acute angle is smaller than a right angle i.e., it can range from 0 to 90 degrees.
During the 3rd century BCE, Euclid laid the foundation for several areas of geometry that are still used today. In his book, “The Elements of Geometry,” Euclid introduced a new way of looking at geometry by using axioms and the axiomatic-deductive method.
He also helped to set the foundation for the system of Cartesian coordinates, which makes it easier to represent and locate lines, points and other shapes in a plane.
Geometry is a critical component of any student’s education as it is used in almost all aspects of the modern world. It is therefore essential to understand how to apply it in real life and how to properly utilize its power. It enhances logical reasoning and deductive thinking as well as increases the student’s thinking ability, which in turn will help them to succeed in their chosen field.
