NCERT Grade 10, Chapter 7: Coordinate geometry
Mathematics NCERT Grade 10, Chapter 7: Coordinate geometry - To start with, a short description of different coordinates are given with reference to what students have learned in class IX.
This chapter lays emphasis on how to find the distance between the two points whose coordinates are given, and to find the area of the triangles formed by three given points. Last, but not least students will also learn how to find the coordinates of the points which divide a line segment joining two given points in a given ratio.
In the first section, readers will learn about the distance formula. It is explained in detail with the help of a diagram. Solved examples are given to make the concept more understandable to students.
Moving further, section formula is given and a special case of finding the mid-point of the line segment is also explained which is important from the examination point of view.
In the last section, area of a triangle is discussed followed by solved example and exercise.
An optional exercise is given at the end of the chapter. After that, the chapter is concluded in 5 points for a quick revision.
