Squaring with Diagonal Measurements

A rectangle is square if the lengths of both diagonals are equal.

Squaring diagonal measurements

A rectangle where both lengths (a) and both widths (b) are equal is square if length of both diagonals are equal!

A = B (1)

where

A, B = diagonal measurements (m, ft ..)
