## NCERT Solutions for Class 10 Maths Chapter 7 Coordinate Geometry Ex 7.2

**Question 1.**

Find the coordinates of the point which divides the join of (-1, 7) and (4, -3) in the ratio 2 : 3.

**Solution:**

**Question 2.**

Find the coordinates of the points of trisection of the line segment joining (4, -1) and (-2, -3).

**Solution:**

**Question 3.**

To conduct Sports Day activities, in your rectangular shaped school ground ABCD, lines have been drawn with chalk powder at a distance of 1 m each. 100 flower pots have been placed at a distance of 1 m from each other along AD, as shown in given

figure below. Niharika runs \(\frac { 1 }{ 4 }\) th the distance AD on the 2nd line and posts a green flag. Preet runs \(\frac { 1 }{ 5 }\) th distance AD on the eighth line and posts a red flag. What is the distance between both the flags? If Rashmi has to post a blue flag exactly halfway between the line segment joining the two flags, where should she post her flag?

**Solution:**

y-coordinate of green flag = \(\frac { 1 }{ 4 }\) x 100 m = 25 m

Coordinates of green flag are P (2, 25)

y-coordinate of red flag = \(\frac { 1 }{ 5 }\) x 100 = 20

Coordinates of red flag are Q (8, 20)

The distance between two points is

The blue flag is in the 5th line, at a distance of 22.5 m.

**Question 4.**

Find the ratio in which the line segment joining the points (-3, 10) and (6, -8) is divided by (-1, 6).

**Solution:**

Let the required ratio be k : 1

**Question 5.**

Find the ratio in which line segment joining A (1, -5) and B (-4, 5) is divided by the x-axis. Also, find the coordinates of the point of division.

**Solution:**

**Question 6.**

If (1, 2), (4, y), (x, 6) and (3, 5) are the vertices of a parallelogram taken in order, find x and y.

**Solution:**

**Question 7.**

Find the coordinates of a point A, where AB is the diameter of a circle whose centre is (2, -3) and B is (1, 4).

**Solution:**

**Question 8.**

If A and B are (-2, -2) and (2, -4), respectively, find the coordinates of P such that AP = \(\frac { 3 }{ 7 }\) AB and P lies on the line segment AB.

**Solution:**

**Question 9.**

Find the coordinates of the points which divide the line segment joining A (-2, 2) and B (2, 8) into four equal parts.

**Solution:**

**Question 10.**

Find the area of a rhombus if its vertices are (3, 0), (4, 5), (-1, 4) and (-2, -1) taken in order.

[Hint: Area of a rhombus = \(\frac { 1 }{ 2 }\) (product of its diagonals)]
