Q1. How will you construct a rectangle PQRS if you know only the lengths PQ and QR?
A rectangle is a special case of a parallelogram whose opposite sides are equal and all the angles are .
Therefore, we know all 4 sides and all 4 angles.
1. Draw PQ. Draw right angle at R and Q. Draw an arc of radius = QR = PS to get the points S and R.
3. Join S to R. PQRS is the required rectangle.)
