What is Heron's Formula, and how do you use it to find the area of a triangle? In this Class 9 Maths video (NCERT/CBSE), Letstute explains Heron's Formula in a simple, logical way - its history, full derivation, and worked examples - so you can calculate the area of any triangle using just its sides. Did you know you can find the area of a triangle without knowing its height? Heron of Alexandria derived a formula that uses only the three sides of the triangle and its semi-perimeter. It's so useful that it works not just for triangles, but for quadrilaterals too. 0:00 Introduction 1:53 History of Heron's formula 2:21 Derivation of Heron's formula 5:59 Examples 6:59 Recap In this video you'll learn: -What Heron's Formula is and who derived it -How to find the area of a triangle using only its sides -The derivation of Heron's Formula -Solved examples using the formula Subscribe and press the bell icon for regular updates: / letstute Website:https://www.letstute.com/ Udemy: https://www.udemy.com/courses/search/...
