## Some Basics about Heron's Formula:

• In geometry, this Heron's Formula which is named after the hero of Alexandria gives us the area of the triangle when we are not provided with the information of all three sides.

• This formula is useful because like all the other formulas of triangles we don't need to find all the angles or other distances of the triangle.

• There are several ways that can prove Heron's formula, like by using trigonometry or incentre and one incircle of triangle and others.

All this knowledge about Heron's formula, several ways which can be used, examples, and other details are provided in RD Sharma. You can solve the questions and get detailed information on all these topics with the solutions provided by Vedantu.
