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 10h of the mid-point of the join of two points to get the co-ordinates of the centroid of a triangle with given vertices.
Important Results in Coordinate Geometry The co-ordinates of the origin are 0, 0 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. If the distance between the points 4, k and 1, 0 is 5, then what can be the possible values of k?
The area of a triangle is 5 sq units. Two of its vertices are 2, 1 and 3, 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 ncert solutions class 10th maths chapter 7 relations 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. The coordinates of a point on the x-axis are of the form x, 0and of a point on the y-axis are of the form 0, y. There is overall summery about coordinate geometry for class 10, which will help the students to know more about this chapter. What are the Objectives of Coordinate Geometry in class 10 Maths? Give some Important Results in Coordinate Geometry?

Find the ratio in which the line segment joining the points -3, 10 and 6, -8 is divided by -1, 6. 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. If 1, 2 , 4, y , x, 6 and 3, 5 are the vertices of a parallelogram taken in order, find x and y.
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. The Questions are based on drawing tangents and draw similar triangles are important topics.

Class 10 maths is having 15 chapters to learn by the students in this academic year. NCERT Solutions are designed in a way that every student can quickly understand the concept into their minds and clarifies all their doubts within a few seconds. The book is self-explanatory and helps students to innovate and explore in maths.
What are the best reference books for class 10 CBSE? The x and y taken together in order is called coordinte of point denoted by x, y. The coordinate of the points on x-axis are of the form x, 0 and the points on the y-axis are of the form 0, y. Coordinate of origin is 0, 0.
The sign of x and y-coordinates in each of the quadrant is shown below:. The distance between any two points P x 1 , y 1 and Q x 2 , y 2 in the plane is given by, Also the distance of the point P x 1 , Ncert Solutions Class 10th Maths Chapter 5 Relations y 1 from the origin is. The coordinates of the point P x, y which divides the line segment joining the points A x 1 , y 1 and B x 2 , y 2 internally in the ratio m 1 : m 2 i.
The coordinates of the mid point P of the line segment joining the points A x 1 , y 1 and B x 2 , y 2 is. Find the distance between the following pairs of points: i 2, 3 , 4, 1 ii -5, 7 , -1, 3 iii a, b , -a, -b Solution: Ex 7. Solution: Ex 7.
