WebCalculate certain variables of a parallelogram depending on the inputs provided. Calculations include side lengths, corner angles, diagonals, height, perimeter and area of parallelograms. A parallelogram is a quadrilateral with opposite sides parallel. A parallelogram whose angles are all right angles is called a rectangle. WebA quadrilateral whose two pairs of sides are parallel to each and the four angles at the vertices are not equal to the right angle, and then the quadrilateral is called a parallelogram. Also, the opposite sides are equal in length. Here, AD = BC (opposite sides) AB = CD (opposite sides) Sum of all the four angles = 360 degrees smith and wesson model 12 serial numbers
