`h = (2*A)/b`

Enter a value for all fields

The **Height of a Triangle** (h = 2A/b) calculator computes the height(h) of a triangle based on the Area (A) and the base (b).

**INSTRUCTIONS**: Choose units, and enter the following:

- (
**A**) Area of Triangle - (
**w**) Width of Base

**Triangle Height (h): **The calculator returns the height (**h**) of the triangle in meters. However this can be automatically converted to other length units (e.g. inches) via the pull-down menu.

The formula for the height of a triangle is:

h = 2A / w

where

- h is the height of the triangle
- A is the area of the triangle
- w is the width of the base of the triangle.

This equations is useful in a wide range of areas from school math to calculating the surface area of any triangle in any industry or hobby.

A **triangle** is a polygon with three sides, three vertices (corners), and three angles. **Triangles **can be classified based on the lengths of their sides and the measures of their angles as follows:

By Side Lengths:

**Equilateral Triangle**: All three sides are equal in length.**Isosceles Triangle**: Two sides are equal in length.**Scalene Triangle**: All three sides have different lengths.

By Angle Measures:

**Acute Triangle**: All three angles are less than 90 degrees.**Right Triangle**: One angle is exactly 90 degrees.**Obtuse Triangle**: One angle is greater than 90 degrees.

The sum of the interior angles of any triangle always adds up to 180 degrees.
