Spaced Revision

Come back to Constructions (Using Ruler and Compass only) after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • An angle can be copied exactly using equal arcs.
  • The bisector divides an angle into two equal parts.
  • 60° is constructed directly.
  • A line segment can be bisected in two ways.
  • The alternative method uses equal arcs from both endpoints.
  • The midpoint divides the segment into two equal parts.
  • A perpendicular can be drawn at a point on a line.
  • A perpendicular can also be drawn from an external point.
  • The arc radius conditions are important for accuracy.

Common Mistakes to Avoid

A 60° angle is made by bisecting another angle.

A perpendicular can be drawn from any point using the same labelled steps, whether the point is on the line or outside it.

The perpendicular bisector of a line segment is just any line that cuts the segment into two equal parts.
