Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Distance on a Number Line and in the XY-Plane, 2. Section Formula and Midpoint Formula, 3. Centroid of a Triangle.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 45 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

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

What to Focus On

  • Distance on a number line is the difference between coordinates.
  • The distance formula in the plane comes from a right triangle.
  • The sign of subtraction does not matter after squaring.
  • Section formula gives coordinates of a point dividing a segment in a ratio.
  • Midpoint formula is obtained by putting m = n.
  • The same idea works on a number line and in the plane.
  • Centroid is the point where the medians meet.
  • Centroid divides a median in the ratio 2:1.
  • First find the midpoint of BC, then apply the section formula on AD.

Common Mistakes to Avoid

The distance formula changes if the order of the points changes, so AB and BA may give different answers.

The slope of the Y-axis is zero, just like the slope of the X-axis.

Any line with positive slope must be slanting downwards from left to right.
