CHAPTER AT A GLANCE
Orienting Yourself: The Use of Coordinates
•Unit: Coordinate Geometry
•Board weightage: this unit carries a small share of the paper; expect one short or 3-mark question on the distance formula or the midpoint (please check the latest sample paper)
•Results from the textbook: distance formula (Baudhāyana–Pythagoras Theorem), midpoint connection, points of trisection, points on a circle
•Most scoring part: distance formula and midpoint questions, which are only substitution and simplification
•Time to revise: about 30 minutes
