NCERT Solutions for Class 9 Maths Chapter 12

NCERT Solutions for Class 9 Maths Chapter 12 Heron’s Formula help students to understand this fundamental chapter of Mathematics. This will create a strong basic understanding of Heron’s Formula which is very popular in geometry-based computations. The different types of triangles and quadrilaterals will give a strong understanding to the students.

Let us discuss the sub-topics in detail.

12.1: Introduction

Students know the process to compute the area of a triangle whose base and height are known. But for general triangle area calculation is difficult. In this chapter, they will learn the method for doing this with the help of the famous Heron’s Formula.

12.2: Area of a Triangle — by Heron’s Formula

Heron’s formula is very helpful for finding the area of a triangle if we know the lengths of all three sides of it. In this formula, we first find the value of half of the perimeter of the triangle and then apply the calculation. This formula is also applicable for the right-angled triangle and isosceles triangle.

12.3: Application of Heron’s Formula in Finding Areas of Quadrilaterals

This formula can be used to find the area of the shapes of quadrilateral by dividing it into triangles on its diagonal. So for quadrilateral all sides and one diagonal are given, then the student can find its area easily. By dividing it into two triangles. Students will learn this method and can apply it to many problems.

12.4: Summary

This chapter is very important for solving various geometrical problems easily. Heron’s Formula is very easy to understand and to apply.
