![]() ![]() The origin divides each of these axes into two halves-positive and negative. The coordinates of the origin are denoted by (0, 0). It is denoted by the letter O, which is used as a fixed point of reference for the geometry of the surrounding plane. The point at which these two number lines intersect each other is known as the point of intersection which is also known as the origin. The Cartesian Plane is a plane formed by the two number lines-vertical and horizontal. The origin, i.e., 0, is greater than the negative numbers and smaller than the positive numbers. Whenever we say that we have started from a point, we always say that we have started from 0 or origin. On the left side of origin, we have the negative numbers and on the right side, we have the positive numbers. ![]() It divides the number line into two parts as given below: The origin on the number line is defined as 0. Hence, it is the point from where we start our measurements. ![]() In terms of temperature, when we go below 0 degrees Celcius, it starts getting colder whereas above 0 it starts getting hotter. On a weighing machine, we measure our weight when the scale shows zero. On a ruler, the 0 is from where we start our measurements hence it is said to be the origin of the scale. In mathematics, especially in the field of coordinate geometry origin is said to be the initial point or the starting point from where we begin our calculations or measurements. ![]()
