Part 1 of Proof of Heron's Formula, Perimeter, Area, and Volume, Geometry

Curated and Reviewed by Lesson Planet

This video is the first installment in a series devoted to exploring Heron's Formula. It is a high-level experience that delves into proof using algebra. It demonstrates a step-by-step process for finding the area of a triangle using Heron's formula and another method. By using two different methods to solve the same problem, the idea that there may be multiple ways to calculate a correct answer is reinforced.
