(a) construct a triangle pqr in which pq is 9cm, angle pqr=pqr=60degrees and qr =10cm. (b) measure and write the length p and r. (c) on your diagram draw the locus within the triangle pqr which are, (1) 3cm from pq. (2) 7cm from r. (3) equidistant from p and r. (d) a point m. within the triangle pqr such that it is nearer to r than to p. less than or equal to 7cm from and less than or equal to 3cm from pq. shade the region in which m must lie.
