Answer» In mathematics, the SIMPLEST form of the PARALLELOGRAM law belongs to elementary geometry. It states that the sum of the squares of the lengths of the four SIDES of a parallelogram equals the sum of the squares of the lengths of the two diagonals. We use these notations for the sides: AB, BC, CD, DAExplanation:i don't know if it is CORRECT are notif it is correct mark me as brainliest
