# Is the diagonal of a square equal to its sides?

A square is a closed two-dimensional figure with four sides and four corners. The length of all four sides is equal and parallel to each other.

## Answer: No, the diagonal of a square is not equal to its sides.

The diagonal of a square is calculated by using the formula: Diagonal of Square (d) = √2 × s, Here 's' is the side of the square.

**Explanation:**

The following image shows a square ABCD with diagonals, AC and BD

The diagonal formula is calculated by using the Pythagoras Theorem.

d^{2} = √(s^{2 }+ s^{2})

= √(2s^{2})

= √2 × s

So, Diagonal of Square (d) = √2 × s

### Therefore, the diagonal of a square is not equal to its sides.
