What is Meant by the Square Diagonal?

In geometry, a square is a quadrilateral whose all four sides are equal and right angles at vertices. It is a two-dimensional plane figure. The diagonal of a square is the line segment joining the opposite vertices of the square. Also, divides it into two congruent isosceles right triangles. Any square has two diagonals and these two diagonals of the square are congruent to each other. They bisect each other and divides each diagonal into two equal parts. The formula to find the diagonal of a square is given by:
Diagonal of square = a√2
a = Length of the side of the square
