State the number of lines of symmetry for the following figures:
$(a)$ An equilateral triangle
$(b)$ An isosceles triangle
$(c)$ A scalene triangle
$(d)$ A square
$(e)$ A rectangle
$(f)$ A rhombus
$(g)$ A parallelogram
$(h)$ A quadrilateral
$(i)$ A regular hexagon
$(j)$ A circle
When a figure is folded in half, along its line of symmetry, both the halves match each other exactly. This line of symmetry is called the axis of symmetry.
$(a)$. An equilateral triangle has three lines of symmetry.
$(b)$. An isosceles triangle has one line of symmetry.
$(c)$. A scalene triangle has no line of symmetry.
$(d)$. A square has four lines of symmetry.
$(e)$. A rectangle has two lines of symmetry.
$(f)$. A rhombus has two lines of symmetry.
$(g)$. A parallelogram has no line of symmetry.
$(h)$. A quadrilateral has no line of symmetry.
$(i)$. A regular hexagon has six lines of symmetry.
$(j)$. A circle has infinitely many lines of symmetry.
