Final answer:
The result of constructing a perpendicular bisector of PQ is two segments, each 30 cm long.
Step-by-step explanation:
In this question, we are given that a perpendicular bisector of PQ is constructed. The length of PQ is 60 cm.
A perpendicular bisector cuts a line segment into two equal halves and creates two segments that are perpendicular to the original line.
Therefore, the result of constructing a perpendicular bisector of PQ is two segments, each 30 cm long.
