How to revise this topic

Start with the linked GCSE topic pages around Constructions, then use the question and flashcard sets below to turn this topic into active recall practice. This topic appears regularly enough that it should be part of a solid GCSE revision cycle.

Sample Flashcards

Angle Bisector
Line dividing angle into two equal parts. Locus of points equidistant from two lines. Compass arcs from vertex crossing both arms.
60° Construction
Draw arc from point, then arc of same radius from first intersection. Creates equilateral triangle principle. All angles 60°.

Sample Questions

When constructing the perpendicular bisector of a line segment AB, what must you do with your compass?

  • A. Set the compass to exactly half the length of AB, then draw arcs from A and B
  • B. Set the compass to more than half the length of AB, then draw arcs from A and B that intersect above and below the line
  • C. Set the compass to the full length of AB and draw a single arc from A
  • D. Set the compass to any radius and draw a single arc from the midpoint of AB
