GCSE Maths Practice: loci-and-constructions

Question 2 of 10

This question reinforces which tools are necessary for perpendicular bisector construction.

‹ ›

\( \begin{array}{l}\text{Which tools are needed to construct a perpendicular bisector?}\end{array} \)

Select all correct options:

Use ruler to draw lines and compass to draw arcs; avoid measuring angles.

Constructing a perpendicular bisector requires only a ruler and compass. The ruler is used for drawing straight lines, and the compass is used to draw arcs from the endpoints. Protractors or calculators are unnecessary for classical constructions. Practising these constructions builds familiarity with classical methods, strengthens geometric reasoning, and prepares students for more complex locus and triangle problems. Visualising each step ensures accuracy. Mastery of these tools is foundational for all compass-and-ruler constructions in geometry.
