Equivalent Rational Numbers – Definition – Examples Rational Numbers A rational number can be represented in the form of p/q, where q is not equal to zero. Equivalent Rational Numbers Two rational numbers are said to be equivalent, if they have same value but can be represented in different forms. We know that if we […]

Rational Numbers – Multiplication In this tutorial, we will learn, multiplication of rational numbers. Multiplication of two rational numbers is just like multiplication of two integers. Product of two or more rational numbers is founded by multiplying the corresponding numerators and denominators of the numbers and writing them in the standard form. Product of numerators […]

Rational Numbers on Number Line Rational Numbers Rational numbers are numbers which can be represented in the form of p/q, where p and q are any two integers and q is not equal to zero(q ≠ 0). Rational Numbers on Number Line Rational numbers can easily represented on number line by following some simple steps. […]

Pentagon – Properties In a pentagon the sum of the internal angles is equal to 540°. In a regular pentagon each interior angle measure is 108°, and each exterior angle measure is 72°. A regular pentagon has five axes of symmetry, each one of them passes through a vertex of the pentagon and the middle […]

Lines of symmetry in a regular Rhombus What is a Rhombus? A rhombus is a quadrilateral whose all the sides are of equal in length, opposite sides are parallel and opposite angles are equal. In other words, a rhombus is a parallelogram with adjacent sides of equal length. What is line of symmetry ? The […]

Lines of symmetry in a regular Square A shape may have more than one line of symmetry depending on its angles and the lengths of each side. For example, a rectangle has two lines of symmetry because it can be folded in half both horizontally and vertically to create mirror images. A regular square is […]
