Finding Area of Quadrialteral using Area of Triangle Formula (dividing Quadrilateral into 2 triangles and finding area)Ĭlick on an exercise link below to study from the NCERT Way.Proving 3 points collinear using Area of Triangle Formula.Finding Area of triangle when coordinates of all 3 vertices are given.Using properties of parallelogram to do some questions on Section Formula (like finding coordinates of a point, when 4 vertices of parallelogram are given).Finding ratio when coordinates of point of intersection is given.Finding coordinates of mid-point of a line using Section Formula.Then, we will learn about Section Formula - Finding coordinates of a point that divides line joining two points in some ratio.Finding points equidistant to given points.Checking if 3 points are collinear using Distance Formula.(To do this, we need to learn properties of parallelogram) Checking if points form a triangle, or an isoceles triangle, or a square, rectangle.How to find distance between two points using Distance Formula.Coordinates of points in x-axis (x, 0) and y-axis (0, y) The formulas of coordinate geometry help in conveniently proving the various properties of lines and figures represented in the coordinate axes.In Coordinate Geometry of Class 9, we learned what is x and y coordinate of a point. All questions have been solved in an easy to understand way with detailed explanation of each and every step.Īnswers to optional exercise is also given Get NCERT Solutions of all Exercise Questions and Examples of Chapter 7 Class 10 Coordinate Geometry. Updated for new NCERT Book for 2023-2024 Boards.
