Question

prove that the square is a quadrilateral​

Answer 1

the square is a quadrilateral as it has 4 sides

Answer 2

Answer:

A square is a quadrilateral because it has four sides.

It is a regular quadrilateral because all four sides and angles are equal.

Explanation:

A quadrilateral is any figure with four sides.

Let's take for example a rectangle (because we have to prove it with squares), it has four sides, so it's a quadrilateral.

And as well as a square has four sides, kites, parallelograms, rhombuses, etc. are also quadrilateral.
