What is Geometry
Christina Sng for Maths@Singapore.
I was fascinated by geometry as a student. Concepts such as how a dot has no length or width. How a line is one-dimensional, having only length, while shapes like triangles, squares, circles, and rectangles are two-dimensional, with lengths and widths. They intrigued me for hours and I found so much joy working on geometry questions.
But first, how does one define geometry?
According to Britannia Kids:
“Geometry is a kind of mathematics that deals with shapes and figures. Geometry explains how to build or draw shapes, measure them, and compare them. People use geometry in many kinds of work, from building houses and bridges to planning space travel.”
There are many aspects of geometry, one of which I’ve already mentioned above, the dimensions. A natural progression follows that shapes such as cubes, cylinders, and spheres are three-dimensions, while tesseracts are four-dimensional analogues of cubes.
Geometry also studies angles, measured in degrees. Angles are made when two lines intersect.
Why are Angles Important?
CueMath explains, “The uses of angles are vast ranging from fun uses like in a game of carrom to more complex ones like planetary motion.”
“Construction, architecture, sports, engineering, art, dance, etc. make use of the concept of angles. That apart, scientists and astronomers depend on the angles that celestial bodies make to study their movement and get down to concrete conclusions.”
Geometry is one of the most important topics in Math for solving real-life problems. Find out more: https://kids.britannica.com/kids/article/geometry/353174
