Coordinate Axes
1. What are the Coordinate Axes in 2D System?
Coordinate axes refers to the system of representing a point, line or a curve on the plane either in 2D or 3D.
2. What are the Signs of Abscissa and Ordinate in 4 th Quadrant?
In 4th quadrant abscissa is positive (+) and ordinate is negative (-).
3. How is Origin Represented in Coordinate Axes System?
Origin in coordinate axes is represented as O(0, 0).
4. Name the Coordinate Axes in 3D System.
The 3D coordinate axes system has 3 axes which are XX’, YY’ and ZZ’.
5. What are the Applications of Coordinate Axes System?
The system of coordinate axes finds application in various fields such as:
- It is used to locate a place on the surface of the Earth in the form of longitudes and latitudes.
- It is also used in navigation system such as Google Maps to determine the coordinates of a person and the places.
- It can be used to location of one object with respect to the other.
6. What do you Mean by Polar Coordinate System?
The system that shows a point by its distance and angle from a reference is called polar coordinate system.
7. Into How Many Parts does the Coordinate Axes Divide the 3D Plane?
In 3D plane coordinate axes divide the plane it eight equal parts called octants.
8. Can we Take Some other Reference Point as Origin in Coordinate Axes System?
Yes, we can take any other reference point as origin but in this case the coordinates of the other points will have to be adjusted according to the new origin.
Coordinate Axes in Coordinate Geometry
Coordinate Axes are the fundamental of the concept in Coordinate Geometry, which is the amalgamation of two branches of mathematics, i.e., algebra and geometry. The basic idea of coordinate geometry is to study the properties of various figures in mathematics i.e., points, lines, curves, etc.
Thus, Coordinate Axes form the basis of coordinate geometry which is the branch of mathematics dealing with the plotting of points, lines, and curves on the coordinate axes system or the Euclidean plane. In this article, we will learn about the Coordinate Axes in detail.
