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 Math / Science
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.
