Diagonal Formula

Diagonal Formula is the formula that is used to calculate the length of the diagonal of any polygon. A diagonal is a slant line that joints two alternate sides of any polygon and finding its length is very important for solving various problems of geometry.

There are different ways for finding the diagonal of any polygon and we use various techniques for that purpose. Using Pythagoras Theorem is one such way. We have to study the Diagonal Formula in Class 8. In this article, we will learn about the Diagonal definition, its formula, various examples, and others related to it.
