Keep this Vedantu NCERT solution handy so that there will be no inconvenience during your study of coordinate geometry. Why is Coordinate Geometry Important? Coordinate geometry helps you to locate the exact location of a point in a plane. Coordinate geometry provides us the link between algebra and geometry through lines, graphs, curves and equations. Coordinate geometry Class 10 holds a weightage of total 6 marks in the final board examination.

Coordinate geometry basically explains four concepts introduction to coordinate geometry, distance formula, section formula and area of triangle. Deeper into Exercises. Each exercise is solved by vedantu experts. Every concept is followed by well defined exercises. Exercises are aimed to test your conceptual knowledge. All the problems of the exercises are based on the concepts explained earlier.

Every problem has a step wise explanation. Students can easily understand the concept used behind the problems. Different types of problems are given to understand the concept thoroughly. Vedantu has studied all the exercise and variety of problems involved in each exercise.

Exercise one is based on how to find distance between two points given on a plane. By the end of this exercise the student will be able to find the distance between two points.

With this property there are different types of problems in the exercise 7. We can calculate the distance between points and prove the types of triangle are isosceles, equilateral or types quadrilateral square, rhombus, rectangle or whether the points are collinear or not. Vedantu provides step wise solutions for every problem with relevant Class 9 Maths Chapter 15 Question Answer File diagrams. Diagrams help us visualize the problem. With the distance formula we can even find the unknown values of x and y coordinate if the distance between the two points are given.

Vedantu provides a stepwise explanation of the solution so that you can solve any similar problems.. Section formula is derived by a well defined theorem. It is basically given on four types of problems. Type1: Finding the section ratio or the end points of the segment when the section point is given. Type 2: Finding the section point when the section ratio is given.

Type 3: Determination of the type of a given quadrilateral. Type 4 : Finding the unknown vertex from given points. Every problem is based on distance formula and section formula. The solutions are given step wise with the conceptual explanation. Which will make the concepts more clear. Earlier we calculated the area of the triangle using formula.

In these chapter 7 Coordinate geometry students have to find the area of the triangle in terms of the coordinates of its vertices. We can find the area of a triangle by finding the sides of the triangle by distance formula and then finding the area of the triangle by Heron's formula. But it becomes tedious if the length of the sides are in the form of irrational numbers. So we prefer to calculate the area in the terms of the coordinates of the vertices of the triangle.

It will also help us to find the type of polygon when the coordinates are given. Using the formula for the area of the triangle we can even calculate the area of the quadrilateral, as the quadrilateral breaks up into two triangles. This exercise covers a total of 10 questions. They are based on four different types. Type 1: Finding the area of a triangle when the coordinates of the vertices are given.

Type 2: finding the area of a quadrilateral when coordinates of its vertices are given. Type 3: Finding collinearity of three points. Type 4: finding the desired results when the three points are collinear.

It has a total of 5 questions. There are a total of 8 questions. Which will be helpful for you to check your knowledge regarding the concepts. Exercise 7 is the test of your knowledge on overall coordinate geometry, students study the concepts and solve therealted problems, but when all the problems related to different concepts are given they get confused. Hence Exercise 7. All the 8 questions are of different types. Solving all these exercises will help you to master the coordinate geometry for Class To locate the position of an object or a point in a plane we require two perpendicular lines.

One of them is horizontal and the other is vertical. The plane is called the cartesian plane or the coordinate plane and the lines are called the coordinate axes. The horizontal line is called the X-axis and the vertical line is called the Y-axis. The abscissa and ordinate of a given point are the distances of the point from Y-axis and X-axis respectively. The coordinates of any point on x-axis are of the form x , 0.

The coordinates of any point on x-axis are of the form 0, y. The distance between points P x 1 , y 1 and Q x 2 , y 2 is given by. Distance of point P x, y from the origin 0, 0 is given by. Offline Apps based on these solutions are also for new session. Join the Discussion Forum to discuss your doubts and respond the questions asked by your friends. 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. 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. What is the distance of point 3,�4 from y-axis? What is the abscissa of any point on y-axis?

What is the distance of point 3,2 from x-axis? A teacher asked three students to stand to form a triangle at the points P �1, 3 , Q 1,�1 and R 5, 1. Suddenly a fourth boy came and shows his interest in participating the activity. She asked him to stand at point mid way between Q and R.
