 Hello and welcome to the session. In this session we will learn parallelogram construction when one side and two diagonals of the parallelogram are given to us. Suppose we need to construct a parallelogram, it's one side of measure 6 centimeters, two diagonals are of measure 8 centimeters. Gram PQRS in which one side say PQ is given of measure 6 centimeters, the two diagonals of the parallelogram PQRS that is the diagonals PR and QS intersect at the point O that this diagonal PR be of measure 8 centimeters and the diagonal QS be of measure 6 centimeters. Now we need to solve a second, our first step would be draw a straight line PQ of the parallelogram which is of measure 6 centimeters to each other, 6 centimeters so this means would be equal. Now the same way we have the diagonal QS be equal to, this is of measure 6 centimeters so OQ and OS comes out to be equal to 3 centimeters. We will locate the point that would be we draw another center and say centimeters as the radius we have drawn the diagonals of measure 3 centimeters are taken here as the center and radius equal to 3 centimeters where this point of intersection of the two arcs remarked as the point O. Next we join is equal to OR and each is equal to 4 centimeters and is equal to O2 4 centimeters each is equal to 4 centimeters as we have OQ and OS of measure 3 centimeters is equal to OS are of equal measure parallelogram in which PQ is of measure 6 centimeters, PLA is of measure 7 centimeters and QS is of measure 6 centimeters those are given to us so this completes the session when two diagonals are given.
