## What is the formula to find the height of an equilateral triangle?

To find the height we divide the triangle into two special 30 – 60 – 90 right triangles by drawing a line from one corner to the center of the opposite side.

This segment will be the height, and will be opposite from one of the 60 degree angles and adjacent to a 30 degree angle.

## How do you find the height in a triangle?

If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.

## What is Heron’s area formula?

Heron’s formula is a formula that can be used to find the area of a triangle, when given its three side lengths. It can be applied to any shape of triangle, as long as we know its three side lengths. The formula is as follows: The area of a triangle whose side lengths are a , b , a, b, a,b, and c c c is given by.
