Sections

  • 8

    Coordinate Geometry

    Coordinate Geometry studies geometry using a coordinate system to locate points on a plane.

    Learning Practice

  • 8.1

    Introduction To Coordinate Geometry

    Coordinate Geometry uses a coordinate system to locate points in a plane with ordered pairs.

    Learning Practice

  • 8.2

    Cartesian Plane

    The Cartesian Plane consists of two perpendicular axes, the X-axis and Y-axis, intersecting at the Origin, used for locating points with ordered pairs.

    Learning Practice

  • 8.3

    Coordinates Of A Point

    The section explains how any point in the Cartesian plane can be represented by ordered pairs (x,y), detailing the significance of the x (abscissa) and y (ordinate) coordinates.

    Learning Practice

  • 8.4

    Plotting Points

    This section describes the process of plotting points on a Cartesian plane using ordered pairs.

    Learning Practice

  • 8.5

    Distance Formula

    The Distance Formula calculates the distance between two points in a Cartesian plane using their coordinates.

    Learning Practice

  • 8.6

    Midpoint Formula

    The Midpoint Formula calculates the midpoint of a line segment defined by two given points in a coordinate system.

    Learning Practice

  • 8.7

    Section Formula

    The section formula allows us to determine the coordinates of a point that divides the line segment between two points in a specified ratio.

    Learning Practice

  • 8.8

    Applications Of Coordinate Geometry

    Coordinate geometry is applied to find distances, midpoints, and divisions of line segments, allowing for the resolution of geometric problems using algebraic methods.
