Answer
The locus is a set of four points that are both 1 cm from line p and 2 cm from line q.
Work Step by Step
Recall, the locus is 1 cm away from p and 2 cm from line q. Thus, first construct the two lines, and then find the four points that are both 1 cm away from p and 2 cm away from q. Note, the book does not ask for calculations, so using a ruler should work for this problem.
