solve this problems​

Answer 1

Answer:

(a) square

(b) rohmbus

(c) parallelogram

(d) isosceles trapezium

Step-by-step explanation:

in 1st case PQ = RS ; PS = QR and PS = SR

QR = SR ; PQ║SR and PS║QR

Hence; PQ = RS = RQ = PS

so, the quadrilateral is square

in 2nd case PQ=QR ; PS=SR ; PQ║SR and PS║QR

So, the quadrilateral is rhombus

in 3rd case; PQ║SR ; PQ=SR ; PS║QR ;PS= QR

so, the quadrilateral is a parallelogram

in 4th case, QR=PS ; PQ║SR ; PQ≠SR

So, the quadrilateral is isosceles trapezium
