GIVEN : In Parallelogram PQRS,
PQ = 4.5 cm
QR = 3 cm
∠PQR = 60o
Step 1: Draw a rough sketch of the parallelogram and mark the given measurements.
Here , we are given only 3 measurements. But as PQRS is a parallelogram , we can also write that RS = PQ = 4.5 cm and SP = QR = 3 cm.
(now we got 5 measurements in total)
Step 2 : Draw ΔPQR using the measures PQ = 4.5 cm , ∠PQR = 60°
and QR = 3 cm.
Step 3 : Locate the 4th vertex ‘S’ using the other 2 measurements PS = 3 cm and RS = 4.5 cm. To locate the fourth vertex ‘S’ , draw an arc , with center P and radius 3cm (PS=3cm).
Draw another arc with center R and radius 4.5cm (RS=4.5cm) which cuts the previous arc at S.
Step 4 : Join RS and PS to complete the required parallelogram.
