Width of Triangle

The Width of a Triangle calculator computes the width of the base of a triangle using the area (A) and the height (h) of the triangle.

INSTRUCTIONS: Choose units and enter the following:

• (A) Area of Triangle
• (h) Height of Triangle

Width of Triangle (w): The width of the base of the triangle is returned in meters.  However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The equation for the base of a triangle is:

      w = 2A/h

where:

• w = width (base of triangle)
• A = area of triangle
• h = height of triangle 

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.
