Question

${\huge{\underline{\small{\mathbb{\pink{DERIVATION \ OF \ PARALLELOGRAM \ LAW}}}}}}$​

Answer 1

Answer:

The Parallelogram law states that the sum of the squares of the length of the four sides of a parallelogram is equal to the sum of the squares of the length of the two diagonals. In Euclidean geometry, it is necessary that the parallelogram should have equal opposite sides. 2(AB)2 + 2 (BC)2 = (AC)2 + (BD)2.
