Download Class 9 Math Exercise 8.2 Notes PDF – Collinearity Test (FBISE & Punjab Boards)
Download Class 9 Math Exercise 8.2 Notes to master the technique of verifying whether three points are collinear using the area of triangle formula. This concept is widely tested in Class 9 coordinate geometry and is essential for solving mixed-word problems, MCQs, and short-answer board questions. These notes follow the Federal Board SLO-Based 2025 syllabus and are equally useful for Punjab boards like BISE Lahore, BISE Gujranwala, and BISE Multan. The method explained involves using the triangle area formula and checking if the result is zero — which confirms collinearity.
Key learning objectives include:
- Identifying collinear points using the triangle area formula.
- Applying formulas to coordinates without drawing scale diagrams.
- Handling positive and negative coordinates effectively.
- Understanding how collinearity connects with slope and line equations.
