Coordinate Geometry

Author:
Gabriel Cheow
Topic:
Circle, Coordinates, Equations, Geometry, Linear Equations, Straight Lines, Tangent Line or Tangent
In this book, you will learn the following:
  • find the coordinates of the midpoint of a line segment;
  • compute the gradient of a line that is parallel or perpendicular to a given line;
  • calculate the area of a rectilinear figure given the coordinates of its vertices using the shoelace method;
  • obtain the equation of a circle given its centre and radius, and vice versa.
