### Coordinate Geometry

Every place on this planet has coordinates that help us to locate it easily on the world map. The coordinate system of our earth is made up of imaginary lines called latitudes and longitudes. The zero degrees 'Greenwich Longitude' and the zero degrees 'Equator Latitude' are the starting lines of this coordinate system. Similarly locating the point in a plane or a piece of paper, we have the coordinate axes with the horizontal x-axis and the vertical y-axis.

Coordinate geometry is the study of geometric figures by plotting them in the coordinate axes. Figures such as straight lines, curves, circles, ellipse, hyperbola, polygons, can be easily drawn and presented to scale in the coordinate axes. Further coordinate geometry helps to work algebraically and study the properties of geometric figures with the help of the coordinate system.

### What Is Coordinate Geometry?

Coordinate geometry is an important branch of math, which helps in presenting the geometric figures in a two-dimensional plane and to learn the properties of these figures. Here we shall try to know about the coordinate plane and the coordinates of a point, to gain an initial understanding of Coordinate geometry.

### Topics Covered in Coordinate Geometry

• The topics covered in coordinate geometry helps in the initial understanding of the concepts and formulas required for coordinate geometry. The topics covered in coordinate geometry are as follows.
• About the Coordinate plane and the terms related to the coordinate plane.
• Know about the coordinates of a point and how the point is written in different quadrants.
• Formula to find the distance between two points in the coordinate plane
• The formula to find the slope of a line joining two points.
• Mid-point Formula to find the midpoint of the line joining two points.
• Section Formula to find the points dividing the join of two points in a ratio
• The centroid of a triangle with the given three points in the coordinate plane.
• Area of a triangle having three vertices in the coordinate geometry
• Equation of a line and the different forms of equations of a line
