๐Ÿ“š Quick Study Guide

  • ๐Ÿ” Definition: A figure has line symmetry if it can be folded along a line so that the two halves match exactly. This line is called the line of symmetry.
  • ๐Ÿ“ Identifying Lines of Symmetry: Look for lines that divide the figure into two identical mirror images.
  • ๐Ÿ“ Examples:
    • A square has 4 lines of symmetry.
    • A rectangle has 2 lines of symmetry.
    • A circle has infinite lines of symmetry.
    • An isosceles triangle has 1 line of symmetry.
  • โž• Transformations: Reflections across the line of symmetry map the figure onto itself.
  • ๐Ÿ’ก Tips: Use a mirror or fold the paper to visualize the lines of symmetry.
