#### 10th Maths Chapter 7 Previous Years Questions

ONE MARK QUESTIONS

1. If the distance between the points (4, k) and (1, 0) is 5, then what can be the possible values of k? [CBSE 2017]

THREE MARKS QUESTIONS

1. The area of a triangle is 5 sq units. Two of its vertices are (2, 1) and (3, -2). If the third vertex is (7/2, y), find the value of y. [CBSE 2017]

2. Show that triangle ABC, where A(-2, 0), B(2, 0), C(0, 2) and triangle PQR where (-4, 0), Q(4, 0), R(0, 4) are similar triangles. [CBSE 2017]

FOUR MARKS QUESTIONS

1. If a≠b≠0, prove that the points (a, a^2), (b, b^2), (0, 0) will not be collinear. [CBSE 2017]

##### Know about Coordinate Geometry

In Coordinate geometry, we study that the distance of a point from the y-axis is called its x-coordinate, or abscissa (abscissa is a Latin word which means cut off) and the distance of a point from the x-axis is called its y-coordinate, or ordinate (ordinate is a Latin word which means keep it in order). Abscissa and ordinate collectively forms coordinate of a point in Cartesian system. The coordinates of a point on the x-axis are of the form (x, 0), and of a point on the y-axis are of the form (0, y). For more question on coordinate geometry, go through NCERT exemplar problems for Class 10 Maths.

###### Historical Facts!

Rene Descartes (1596 – 1650) was a French philosopher, mathematician whose work ‘La geometrie’ includes his application of algebra to geometry from which we now have Cartesian geometry.

##### What is the main objective of Chapter 7 Coordinate Geometry in class 10 Maths?

Objectives of Coordinate Geometry

To find the distance between two different points whose co-ordinates are given and finding the co-ordinates of a point, which divides the line segment joining two points in a given ratio internally. To find the co-ordinates of the mid-point of the join of two points to get the co-ordinates of the centroid of a triangle with given vertices.

##### How can one get good marks in class 10 Chapter 7 Maths?

For examination purpose, we have to do only first three exercises. Exercise 7.4 is an optional one, given only for extra practice. Out of exercise 7.1, 7.2 and 7.3, if a student complete the first two exercise thoroughly he can score good marks in entire chapter 7 of class 10 Maths.

##### What are the Important Results in Chapter 7 Class 10 Maths Coordinate Geometry?

Based on class 10 Maths Chapter 7, the Important Results in Coordinate Geometry are as follows:

1. The co-ordinates of the origin are (0, 0)

2. The y co-ordinate of every point on the x-axis is 0 and the x co-ordinate of every point on the y-axis is 0.

3. The two axes XOX’ and YOY’ divide the plane into four parts called quadrants.

##### What are the important examples of class 10 Maths chapter 7 Coordinate Geometry?

Example number 4, 5, 9, 10 and 14 are considered as important examples of 10th Maths Chapter 7 Coordinate Geometry as these are frequently asked in board exams as well as school tests.

##### What are the main topics to study in chapter 7 Coordinate Geometry Class 10 Maths?

In chapter 7 (Coordinate Geometry) of class 10th math, Students will study:

1) Distance Formula (To find distance between two points P(x₁, y₁) and Q(x₂, y₂)).

2) Section Formula.

3) Area of triangle (when only vertices of triangle are given).

##### How many exercises are there in chapter 7 of 10 Maths?

There are 4 exercises (exercise 7.1, 7.2, 7.3 and 7.4) in chapter 7 (Coordinate Geometry) of class 10 maths and exercise 7.3 has least number of questions (only 5 questions).

##### Does chapter 7 (Coordinate Geometry) of class 10 math contain any Theorem?

No, chapter 7 (Coordinate Geometry) of class 10 math doesn’t contain any Theorem.

##### Is there any optional exercise in chapter 7 (Coordinate Geometry) of 10th Math?
