# 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.
