In quadrant 1, the sign of the x-axis is positive, and the y-axis is also positive. Did you follow up on the universal rule mentioned above? Representing the coordinates in a coordinate plane becomes easier when one has understood the concept of negative and positive axes. Now, can we locate the coordinates in coordinate plane quadrants? Coordinate plane quadrants: Representing coordinates in a coordinate plane In the same way, the top of the y-axis is positive, and the bottom of the y-axis is negative. ![]() The universal rule is: that the right of the x-axis is positive, and the left side of the x-axis is negative. In coordinate plane quadrants, the sign of the coordinates changes. What are the coordinates of the origin? Since the origin is the starting point, how do we represent a starting point? By the number zero, right? Therefore, the coordinates of the origin are (0, 0). The standard form of representing the coordinates in a coordinate system is known as an ordered pair. Coordinates are written as (x, y), where x is the value from the origin in the direction of the x-axis, and y is the value from the origin in the direction of the y-axis. Coordinates are a set of numbers that represent the location of an object. But how do you represent the coordinates? Is it that important to learn to represent coordinates? Certainly, it is! The coordinates differ in each of the coordinate plane quadrants mentioned above. We also know the coordinate plane quadrants. Now, we know the parts in a coordinate plane. Learning to represent coordinates in a coordinate plane The bottom left is the third quadrant, and the bottom right is the fourth quadrant. The top left is known as the second quadrant. The top right division is known as the first quadrant. So, we can say the whole coordinate system consists of four quadrants. These four divisions are known as quadrants. When these two lines intersect, they make four divisions of the entire coordinate plane. Origin is the starting point of any coordinate plane. These axes meet up at a common point, called origin. The horizontal axis is the x-axis or the abscissa, whereas the vertical axis is the y-axis or ordinate. The two lines, vertical and horizontal that go never-ending in a coordinate plane are known as axes. Have you seen a coordinate plane yet? What does it look like? A coordinate plane consists of axes, origin, and quadrants. Why a rectangular coordinate system? Because the entire plane looks like a rectangle! Before moving further to understanding the coordinate plane, let us see the parts in a coordinate system. Rene Descartes was the first to define a rectangular coordinate system by which we can represent each point with the help of numbers, called coordinates. The two-dimensional coordinate plane is the Cartesian plane, named after a well-known French mathematician, Rene Descartes. They are perpendicular to each other, meaning they will form a 90-degree angle at their meeting point. The horizontal axis is known as the x-axis, and the vertical axis is known as the y-axis. A coordinate plane is a two-dimensional (three-dimensional, while considering 3D objects) plane consisting of vertical and horizontal axes. And these coordinates are represented in a coordinate plane. What is a coordinate plane: Learning geometry in a new wayĪs mentioned above, coordinates help us locate an object anywhere in the world. Curious to know what coordinates are or what is a coordinate system? Continue reading further to learn more. That way, it is easier to locate the object within no time. ![]() Sailors use the coordinate plane concept to track their way back home and draw maps. What is the use of representing the shapes in such a way? In practical life, we need to know the coordinates of any place or position of a person. ![]() But, do we know that these objects can be represented on paper by specific knowledge of axes and planes? We draw shapes in a 2D plane, i.e., only in two directions x and y. Even many shapes are two-dimensionally present around us. ![]() We have acknowledged the fact that various objects around us are three-dimensional.
