Which quadrilateral will always have 4-fold reflectional symmetry

A quadrilateral is a 2-dimensional closed figure having 4 sides of straight lines. The quadrilateral has four sides, four vertices, and the sum of all four interior angles is 360 degrees.

The types of a quadrilateral are:

The quadrilateral having 4-fold reflectional symmetry is SQUARE.

Reason:

The square can be folded into halves either the fold over the vertical lines or the fold over the horizontal lines or the fold-over of either of the diagonals.

The crease of the fold in the square will always create a reflectional symmetry.

Square

Square can be folded in half:

- over the vertical line

-over the horizontal line

-over either diagonal (2 diagonals)

So the square has 4 lines of symetry

Rectangle  2 lines

Trapezoid  1 line

Parallelogram   no lines
