* 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. | |||
