Linear Symmetry

Linear Symmetry
A figure is symmetrical about a line if the line divides the given figure into two identical halves. The line is called the axis of symmetry or line of symmetry.

    Examples
  1. A line segment is symmetrical about its perpendicular bisector.
  2. An angle is symmetrical about its bisector.
  3. An equilateral triangle has three lines of symmetry. These are angular bisector of each of the angles.
  4. A square and a rectangle has four and two lines of symmetry.
  5. A rhombus has two lines of symmetry. These are its diagonals.
