Parallelogram — is a quadrangle in which the opposite sides are pairwise parallel, that is, they lie on parallel lines. Particular cases of a parallelogram are a rectangle, a square, and a rhombus.

Knowing the diagonal of a parallelogram and one of its sides, you can find the second side. To do this, you need to extract the square root of half the sum of the squares of the diagonals minus twice the square of the known side.
