Card 1Introduction

What is Coordinate Geometry?

Answer

Coordinate Geometry is a branch of mathematics that deals with the study of geometry using coordinates. It was developed by French mathematician René Descartes. It helps us locate and describe the pos

Card 2Cartesian System

What are coordinate axes and what are they called?

Answer

Coordinate axes are two perpendicular lines used to locate points in a plane. The horizontal line is called the x-axis and the vertical line is called the y-axis. Together, they form the coordinate sy

Card 3Cartesian System

What is the origin in coordinate geometry?

Answer

The origin is the point where the x-axis and y-axis intersect. It is denoted by the letter O and has coordinates (0, 0). It serves as the reference point for measuring distances along both axes.

Card 4Quadrants

How many quadrants are formed by coordinate axes and how are they numbered?

Answer

The coordinate axes divide the plane into four parts called quadrants. They are numbered I, II, III, and IV in anticlockwise direction starting from the positive x-axis. Each quadrant represents a dif

Card 5Quadrants

What are the signs of coordinates in each quadrant?

Answer

Quadrant I: (+, +) - both x and y coordinates are positive Quadrant II: (-, +) - x coordinate is negative, y coordinate is positive Quadrant III: (-, -) - both x and y coordinates are negative Quadran

Card 6Coordinates

What is the x-coordinate of a point also called?

Answer

The x-coordinate of a point is also called the abscissa. It represents the perpendicular distance of the point from the y-axis, measured along the x-axis. It is positive in the positive direction and

Card 7Coordinates

What is the y-coordinate of a point also called?

Answer

The y-coordinate of a point is also called the ordinate. It represents the perpendicular distance of the point from the x-axis, measured along the y-axis. It is positive in the positive direction and

Card 8Coordinates

How do we write the coordinates of a point?

Answer

The coordinates of a point are written as (x, y), where x is the x-coordinate (abscissa) and y is the y-coordinate (ordinate). The x-coordinate is always written first, followed by the y-coordinate, e
