Decimal Numbers – Place Value Chart Decimal Number We know that decimal numbers means a writing fractions or a number with denominators are powers of 10. In a decimal number decimal point dot (.) is called decimal point. Decimal point separates the whole number part and the fractional part. In below example 287 is whole […]

The number after the decimal is called the decimal part and the number before the decimal point is called the whole or integral part. First we take a plane sheet which represents one whole. […]

Opposite sides, AB = CD and AC = BD 2. Opposite angles are equal. Opposite angles are ∠A = ∠D and ∠B […]
Read More →We use many objects in our daily life, which are round in shape, such as wheels of a vehicle, sun, moon, a dinner plate, button of shirts etc. These are real examples of a circle. Let’s study about circle and it’s parts. Definition: 1. Circle A circle is a collection of […]

First we will place a dot at the intersection of X and Y axis, which is the center of the Cartesian coordinate and known as the origin. From the origin, move 2 units going right. Our point is […]

Read More →History of Coordinate Geometry The Cartesian system or the rectangular coordinate system was invented in seventeenth century by Rene Descartes, the great French philosopher and mathematician. The coordinate system is also called the Cartesian system. Geometry was well developed to describe the dimension of an object, but it does not describe the position of an object. So, to […]
Read More →What is Ordinate Ordinate is the value of the Y coordinate on a coordinate plane. or Ordinate is the value of the Y axis on a coordinate plane. In a coordinate plane, the Ordinate is the Y coordinate of a point. The Vertical line is called the Y axis. The distance of a point from the X axis is called its Y coordinate or Ordinate. The Ordinate always comes […]

The Horizontal line is called the X axis, and abscissa is the value of the X axis on a coordinate plane. The distance of a point from the Y axis […]
