A triangle is a regular polygon and the closed two-dimensional figure having 3 sides, 3 vertices, and 3 angles. The sum of interior angles adds up to 180 – degree and the sum of the exterior angles would make up 360-degrees. Three most popular triangles based on the side length are given as – Equilateral […]

Equilateral Triangle Formula The Equilateral Triangle is another common type having all three sides are equal and the interior angles are also the same i.e. 60-degree. The equilateral Triangle Formulas in geometry are given as – \[ Area \;of \;an \;Equilateral \;Triangle = \frac{\sqrt{3}}{4}a^{2}\] \[ Perimeter \;of \;an \;Equilateral \;Triangle = 3a\] \[ Semi \;Perimeter […]

What is Triangle? In geometry, the triangle is the most popular topic and this is necessary to understand for early school students and competitive exam studies. So, what is a Triangle exactly? A Triangle is the most simpler form of a polygon having 3 sides or we can say that the triangle is a two-dimensional […]

The Perimeter of Hexagon Formula Hexagon is the polygon that has six equal sides and the six edges. Hexa is a Greek word whose meaning is six. Naturally, when all six sides are equal then perimeter will be multiplied by 6 of one side of the hexagon. Abd each internal angle is measured as 120-degree. […]

Trapezoidal Rule Formula A quadrilateral with two parallel sides is called the Trapezoid. It may also be named as the Trapezium in major parts of the world.  The two sides that are parallel in Trapezoid are known as bases and the non-parallel sides are known as the lateral sides. And the distance between two parallel […]

What is Sphere? You must have seen students playing with footballs, tennis balls, table tennis etc. These all are the examples of Sphere in 3-dimensional geometry. When a semi-circle is rotated across its diameters then it will become a Sphere. The radius of Sphere would be equal to the radius of a semi-circle. A Sphere […]

What is Cube? A cube is a three-dimensional figure with six square faces. When it is moving through space then it will become thicker. All cubes have six sides, one is the top, one is the bottom, and rest four sides make a square together. To count the sides of the cube, you have to […]

Cube Root Formula Before we look at the actual sum and differences of cube formula, you first need to know cube Formulas are necessary to study. This is a part of simple mathematics itself and learned during early school days. It is commonly used for complex calculations where cubes are given or problem is stated […]

Discount Formula Calculation of discount is one of most proficient mathematical skills that you can learn. You can apply it to the restaurants, shopping malls, and setting rates for your products. The actual way to calculate discount is multiplying original price with the discount percent rate. To calculate the selling price, you just have to […]
