GCSE Maths Practice: loci-and-constructions

Question 3 of 10

This question introduces the compass as a fundamental construction tool.

‹ ›

\( \begin{array}{l}\text{Which tool is used to construct the perpendicular bisector of a line segment?}\end{array} \)

Choose one option:

Draw arcs from each end of the segment; connect intersections with a straight line.

To construct a perpendicular bisector, a compass is used to draw arcs from both ends of the line segment. The intersection points of these arcs determine the line that is equidistant from both ends. Practising compass constructions builds precision, spatial reasoning, and understanding of equidistance. Mastery is essential for classical geometric constructions and locus problems. Students should draw multiple examples, label arcs, and connect intersection points to reinforce the concept. Knowing which tool to use ensures efficiency and accuracy in constructions.
