(a) Using ruler a pair of compasses only, construct: (i) a trapezium PQRS such that |PQ| = 6.8 cm, < PQR = 120\(^o\), QR||PS, |PS| =10.6 cm, and IPRI = 93 cm; (ii) locus \(l_1\) of points equidistant from P and R; (iii) locus \(l_2\) of points equidistant from Q and R (b) Measure: (i) |QR|; ii. < PSR ii. < PSR iii. |QY|, where Y is the point of intersection h and h.
