Exam points

  • Reflect each vertex across the stated straight mirror line, keeping its perpendicular distance from the line unchanged.
  • For a line such as y = k, keep x unchanged and transform the y-coordinate to 2k − y.
  • Plot the reflected vertices and join them in the original order to form the image.
