Coordinate Geometry

Introduction to Coordinate Geometry

# An Overview

**Need for Coordinate Geometry**

Consider a situation wherein we have the students of a class sitting in different rows and we need to locate the position of one particular student. Let us suppose that this student is sitting in the second row. **Using this information, can we ascertain the student’s exact location?**

No, we cannot. The given information is insufficient. For us to be able to locate this student in the class, we also need to know the column in which he/she is sitting. So, we require two [[mn:glossary]]variables[[/mn:glossary]] to define the student’s position—one for the row and the other for the column.

Such situations—wherein we require two attributes to locate points, objects, etc.—can be dealt with by using coordinate [[mn:glossary]]geometry[[/mn:glossary]]. It is the geometric system in which the positions of points on a plane are described using ordered pairs of numbers.

Topics to be covered in this lesson:

•Terminology related to coordinate geometry

•Convention of signs in the different quadrants of the Cartesian plane

•Reading the positions of points plotted on the coordinate plane
