# NCERT Solutions Class 10 Maths Chapter 7 Exercise 7.3 Coordinate Geometry

NCERT solutions for class 10 maths chapter 7 exercise 7.3 Coordinate Geometry takes the area of a triangle learned in previous chapters and translates it to the cartesian system. Using the area of a trapezium we can derive the area of a triangle given the x and y coordinates of the three vertices. The exercise consists of 5 questions, out of which three are easy and two are moderate. These are based on calculating the area of a triangle. The simple ones directly call for the application of the formula to either find a missing coordinate or to determine the area of a triangle whereas the intermediate ones might have a quadrilateral that needs to be divided into two triangles to establish the required dimensions. The NCERT solutions class 10 maths chapter 7 exercise 7.3 is one of the most scoring exercises, as the questions are simple to solve using the given formula.

To attempt the problems successfully kids must always draw the figure on a graph. In addition to this, some sums see the use of the various properties of a triangle hence, they must revise those before attempting such problems. This will help them analyze the problem in one go and reduce the room for mistakes.

## NCERT Solutions Class 10 Maths Chapter 7 Exercise 7.3 Tips

NCERT solutions class 10 maths chapter 7 exercise 7.3 Coordinate Geometry will help us delve deeper into the concept of the area of a triangle. We have already explored the concept of a trapezium in the previous classes. In this exercise, we will use this concept to derive the formula of the triangle. This can be done by drawing perpendiculars and using the algebraic formula for the area of the triangle i.e., ½ ( base x height). The derivation of this formula has been explained in detail in the NCERT solutions.

NCERT solutions class 10 maths chapter 7 exercise 7.3 will encourage students to use real-life references to understand concepts. Kids can also time themselves while solving this exercise as it can help them increase their overall speed. This does not only help in school exams but also in olympiads and various other competitive exams.
