In the figure, PQ and QR are chords of the circle PQR. QRS is a straight line and PR is equal to RS, < PSR is 20o. What is the size of <POQ.
In the parallelogram PQRS, PE is perpendicular to QR. Find the area of the parallelogram.
From the figure, calculate TH in centimeters
In diagram, PQ || ST and < PQR = 120o, < RST = 130o, find the angle marked x
In the figure, PQST is a parallelogram and TSR is a straight line. If the area of \(\bigtriangleup\)QRS is 20cm2, find the area of the trapezium PQRT.
