 Hello and welcome to the session. In this session we discussed the following question which says construct a parallelogram PQRS in which PQ is equal to 5 centimeters, QR is equal to 4 centimeters and angle Q is equal to 60 degrees. So we have to construct the parallelogram PQRS in which we are given the two sides and the included angle. Let's proceed with the solution. First of all let us make a rough figure for the parallelogram PQRS. This is the parallelogram PQRS in which we have PQ as 5 centimeters, QR as 4 centimeters and the angle Q included between the two sides PQ and QR as 60 degrees. So we need to now construct this parallelogram PQRS. We will do this construction step by step. We will follow some steps of construction. In the first step we draw a straight line PQ equal to 5 centimeters. This is the straight line PQ of measure 5 centimeters. In the next step at Q draw a straight line Qx making angle PQx equal to 60 degrees. So we have drawn this straight line Qx such that this angle PQx is of measure 60 degrees. Now in the next step we would locate the point R where this QR is of measure 4 centimeters. So in the next step with Q as center draw an arc with radius 4 centimeters cutting off Qx. So we have drawn this arc with Q as the center and radius equal to 4 centimeters such that this arc cuts the straight line Qx at the point R. Thus we have this QR as 4 centimeters. Now next we need to locate the point S. As we know that in a parallelogram opposite sides are equal. So this means if PQ is 5 centimeters so RS would also be 5 centimeters and if QR is 4 centimeters so PS would also be 4 centimeters. In the next step we have with P as center draw an arc with radius 4 centimeters. So we have drawn this arc with P as center and radius as 4 centimeters. In the next step we have with RS center draw an arc with radius 5 centimeters. So this green arc is the arc that we have drawn taking RS the center and radius equal to 5 centimeters. Then let the two arcs intersect at S. So this point of intersection of the two arcs is the point S. Next we join PS and RS. So we have joined PS and RS. This PS is equal to 4 centimeters and RS is equal to 5 centimeters. Thus this PQRS is the required parallelogram in which we have PQ equal to 5 centimeters, QR equal to 4 centimeters and the angle included between the two sides that is angle Q is 60 degrees. This completes the session. Hope you have understood the solution of this question.
