Study Plan

1
Day 1–2

Learn the Theory

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 38 questions available for this chapter.

Day 7

Spaced Revision

Come back to Constructions after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Construction is done using ruler and compass.
  • The chapter builds on earlier construction of triangles and quadrilaterals.
  • Accuracy of steps is more important than freehand drawing.
  • An external point gives two tangents.
  • A point on the circle gives one tangent.
  • A point inside the circle gives no tangent.
  • First join O and P by the segment OP.
  • Draw the perpendicular bisector of OP.
  • M is the midpoint of OP.

Common Mistakes to Avoid

Two tangents can always be drawn to a circle from any point.

The external point used in the construction is different from the point joined to O in Step 1.

The auxiliary circle is the final circle needed in the answer.
