FAQs on RS Aggarwal Solutions Class 8 Chapter-22 Introduction to Coordinate Geometry (Ex 22B) Exercise 22.2
1. What is the definition of Coordinate geometry?
Coordinate geometry, also called Cartesian Geometry, is a branch of Mathematics that deals with the position of points on a plane, which is determined using an ordered pair of numbers called coordinates.
It is the study of the geometric properties of figures using a coordinate system. The coordinate system used in plane coordinate geometry is based on two perpendicular number lines, called the x-axis and y-axis.
2. What is a coordinate plane in Coordinate Geometry?
A coordinate plane is a flat surface that has an X and a Y-axis. The coordinate plane is used to graph data; the X-axis is measured left to right, and the Y-axis is measured up and down. Coordinate geometry is used to find points on the coordinate plane, given an ordered pair of numbers. For Example, if you are given the ordered pair (2,6), you can locate those two points on the coordinate plane by drawing an imaginary line with 2 on the X-axis and 6 on the Y-axis.
3. What are the four different types of coordinate planes?
A coordinate plane is an X-Y plane. The X-axis passes from left to right, and the Y-axis passes from bottom to top.
The Four Different Types of Coordinate Planes are:
First quadrant: positive x and positive y.
Second quadrant: negative x and positive y.
Third quadrant: negative x and negative y.
Fourth quadrant: positive x and negative y.
4. What does Coordinate Geometry have to do with real life?
Coordinate Geometry has many applications in real life. To begin with, it has applications in general geometry. In addition, it has applications in graph theory and algebraic geometry. It also has applications in computer graphics, robotics and physics. It is essential in cartography, navigation and map-making.
5. Is Coordinate geometry easy to prepare for Exams like JEE?
Yes, in fact, coordinate geometry is one of the easiest and highest-scoring JEE Mathematics topics. It requires only basic concepts of Mathematics like number systems, algebra, geometry, etc. It makes use of the Cartesian coordinate system and its properties.
