symmetry

• line of symmetry divides a shape into equal parts
• ex.
  • Square: A square has four lines of symmetry – one horizontal, one vertical, and two diagonal lines.
  • Circle: A circle has an infinite number of lines of symmetry, as any diameter passing through the center divides the circle into two equal halves.
  • Rectangle: A rectangle has two lines of symmetry – one horizontal and one vertical.
  • Equilateral Triangle: An equilateral triangle has three lines of symmetry – one for each median.
