Topics in Symmetry

1

1. Concept of Symmetry

  • A figure has symmetry if it can be divided into two identical halves by a line.
  • The line that divides the figure into two mirror-image halves is called the **line of symmetry** or **axis of symmetry**.
  • When a figure is folded along its line of symmetry, both halves match exactly.

2. Lines of Symmetry in 2D Shapes

  • Different shapes have different numbers of lines of symmetry.
  • A line segment has 1 line of symmetry — its perpendicular bisector.
  • An angle with equal arms has 1 line of symmetry — its angle bisector.

3. Symmetry in Letters and Alphabets

  • Some English letters have vertical symmetry, some have horizontal, and some have both.
  • Letters like A, M, T, U, V, W, Y have vertical symmetry.
  • Letters like B, C, D, E have horizontal symmetry.

4. Constructing Symmetric Points and Lines

  • To find a point symmetric to a given point across a line, draw a perpendicular from the point to the line and extend it equally on the other side.
  • The line of symmetry is the perpendicular bisector of the segment joining a point and its image.
  • To construct the line of symmetry between two symmetric points, draw the perpendicular bisector of the segment joining them.
