Question

The number of lines of symmetry for rectangle are/ is ____.

Answer 1

The "Line of Symmetry" (shown here in white) is the imaginary line where you could fold the image and have both halves match exactly.

$\Rightarrow$ In the figure there are two lines of symmetry.

$\Rightarrow$ The figure is symmetric along the lines $m$ and $n$ joining the midpoints of opposite sides.

$\therefore$ Rectangle has $2$ lines of symmetry
