About NCERT Class 10 Maths Chapter 7 Ex 7.2 

 

You learn the two most important things about coordinate geometry in this chapter. One is the distance formula and the other is the section formula. Exercise 7.2 is based on the section formula. 

 

According to the section formula, The coordinates of the point P(x, y) which divides the line segment joining the points A(x1,y1) and B(x2, y2), internally, in the ratio m:n are given by:

 

Also, there is a special case of the section formula. According to it, the midpoint of a line segment divides the line segment in the ratio 1:1. Therefore, the coordinates of the midpoint P of the join of the points A(x1, y1) and B(x2, y2) are given by:

 

 

Types of questions included in NCERT Class 10 Maths Chapter 7 Exercise 7.2:

 

All the questions in this exercise are word problems. In most of the questions, you are given different coordinates of line segments and a ratio by which one line segment divides another. You have to find the points of intersection and their coordinates. 

 

In some questions, you have to find the ratio by which one line segment divides another. For instance, in question number 9, you have to find the coordinates of the points that divide a line segment joining A(– 2, 2) and B(2, 8) into four equal parts.

 

Some questions of this exercise are of an advanced level where you have to apply your analytical skills to find out the solution. For example, in question number 7, you are given that AB is the diameter of a circle and you are given the coordinates of B and the centre of the circle. You have to find the coordinates of point A. 

 

Tips to solve exercise 7.2 of Class 10 Maths Coordinate Geometry:

• You must read the question carefully and underline the key points of the question. Then, you should write down the key points as information given to you. 

• If possible, draw a rough diagram of the question so that you can get an idea of how to approach the solution. 

• Make sure to double-check the negative and positive signs of the coordinates. Many times students write down the wrong coordinates and get incorrect answers. 

• Make sure to remember the section formula correctly. If you make one mistake in the formula, you might get a completely different answer. 

• In case of any doubts in this exercise, you must refer to the NCERT Solutions by askIITians.
