๐Ÿ“š Quick Study Guide

  • ๐Ÿ” A reflection in mathematics is a transformation that flips a figure over a line, called the line of reflection.
  • ๐Ÿ“ The reflected image is the same distance from the line of reflection as the original figure.
  • โ†”๏ธ Reflections preserve size and shape, meaning the original figure and its reflection are congruent.
  • ๐Ÿ”ข In a coordinate plane, reflecting a point $(x, y)$ over the x-axis results in the point $(x, -y)$.
  • ๐ŸŒŒ Reflecting a point $(x, y)$ over the y-axis results in the point $(-x, y)$.
  • ๐Ÿงฎ Reflecting a point $(x, y)$ over the line $y = x$ results in the point $(y, x)$.
  • ๐Ÿ’ก Understanding reflections helps in various fields like computer graphics, physics, and art.
