Height of Triangle

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.
