Question

How many lines of symmetry does a regular quadrilateral have? What is the order of

rotational symmetry of it?​

Answer 1

Answer:

So the square has four lines of symmetry. The rectangle has only two, as it can be folded in half horizontally or vertically: students should be encouraged to try to fold the rectangle in half diagonally to see why this does not work. The trapezoid has only a vertical line of symmetry.
