How to Calculate Perimeter Calculating the perimeter of a shape involves adding up the lengths of all its sides. The perimeter is the total distance around the outside of a shape, and it’s an important concept in geometry. Let’s explore how to calculate the perimeter for different shapes in detail. 1. Perimeter of a Rectangle […]
Read More →What are 2D shapes ? 2D shapes, or two-dimensional shapes, are flat shapes that have only two dimensions, length and width. They do not have depth or height. These shapes can be drawn on a flat surface, like a piece of paper, and they include various types of polygons and circles. Here’s a detailed explanation […]
Read More →Area – Definition – Formula – Example let’s dive into the concept of area in math with a comprehensive explanation, formula, examples, and units. Definition Area is the amount of space inside the boundary of a two-dimensional shape. It is measured in square units, which represent the number of squares of a given size that […]
Read More →Area in Math In mathematics, the area refers to the amount of space inside the boundary of a two-dimensional shape. It’s like measuring how much surface the shape covers. Here’s a detailed explanation with some examples: Understanding Area Basic Concept: Area measures the size of a surface. It’s usually expressed in square units (e.g., square […]

An object is said to have a line of symmetry when one half of it is the mirror image of the other. […]

A rhombuses is a type of parallelogram. All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all […]
Read More →Convex Polygons: Definition – Examples and Properties All polygons is either convex or concave. A polygon will be convex or concave, it depends on the measure of their angles. If the measures of all interior angles is less 1800 than the polygon is convex, otherwise the polygon is concave. […]

Diagonals of Polygon’s A polygon’s diagonal’s are line segments, that joining from one corner to another corner. Formula for number of diagonals = n(n-3)/2 where n is number of sides or […]
Read More →Universal Set In this lesson, we will learn what is a universal set and representation of universal set in venn diagrams. Definition: The set that contain all the elements of a given collection, and therefore all sets are subset of the Universal Set is known as the Universal Set. Symbol: Universal Set is represented by symbol “U”. […]
