Topics in Reflection

1

Cartesian Coordinate System Review

  • The cartesian plane is divided by two perpendicular lines: X-axis (horizontal) and Y-axis (vertical)
  • These axes intersect at the origin O(0,0) and divide the plane into four quadrants
  • Every point P has coordinates (x,y) where x is the abscissa and y is the ordinate
2

Basic Concept of Reflection

  • Reflection creates a mirror image of an object across a line or through a point
  • The reflecting line is called the axis of reflection or mirror line
  • Distance from object to mirror line equals distance from mirror line to image
3

Reflection in Coordinate Axes

  • Reflection in X-axis: y-coordinate changes sign, x-coordinate remains same
  • Reflection in Y-axis: x-coordinate changes sign, y-coordinate remains same
  • Points on the axis of reflection are invariant points
4

Reflection in Lines Parallel to Axes

  • Line parallel to X-axis has equation y = a (constant y-value)
  • Line parallel to Y-axis has equation x = a (constant x-value)
  • Distance from point to line equals distance from line to reflected point
