How to Find Diagonal of a Square?

A square is defined as a closed two-dimensional figure with four sides and four corners. The length of all four sides is equal and parallel to each other. The diagonal of a square is a line segment that joins any two of its opposite vertices.

Diagonal of a square = √2 a, where 'a' is the length of side

Solved Example:

Find the diagonal of a square whose side length is 8 units?

Solution:

Diagonal of a square = √2 a

= √2 × 8

=  1.414 × 8 

= 11.312 units

Therefore, the diagonal of a square is 11.312 units.

Similarly, you can try the calculator to determine the diagonal of a square if:

1) side length = 16 units

2) side length = 11 units
