The concept of side in Maths is something very fundamental, and this concept should be picked up almost spontaneously by kids as they play around with toys or are curious about objects. The knowledge of side in Mathematics or in general is very basic and should be absorbed and retained for life. Let us learn more about side definitions in Maths in this article.
Meaning of Side in Maths
In any two-dimensional figure, the line segment that joins two vertices is known as a side of the figure. In the case of a three-dimensional figure, the side that we are talking about will be called an edge. Different shapes have different numbers of sides and side lengths. Let us see a few examples.
Examples of Sides of a Few Two-Dimensional Figures
The minimum number of sides required to form a two-dimensional shape is 3, which gives us a triangle. The next number would be 4, giving us a quadrilateral, and so on. Let us go through a few examples to understand better.
Sides of an equilateral triangle
Sides of a rectangle
Side of a regular pentagon
Point to Note
Figures like circles, which have curved boundaries, do not have sides. A circle is bounded by a curved line called the circumference.
Sides are the line segments that join the vertices in any two-dimensional figure. They form the boundaries of the figure and are used to formulate measures like area, perimeter, and so on. It is a basic concept that should remain clear in the minds of children throughout their academic years and even further.
