The Area of a Equilateral Triangle calculator computes the area of a triangle given the length the triangle's three equal sides.
INSTRUCTIONS: Choose units and enter the following:
Triangle Area (A): The calculator returns the area of the equilateral triangle in square meters. However, this can be automatically converted to compatible units via the pull-down menu.
The formula for the area of an equilateral triangle is:
`A = sqrt(3)/4 * a^2`
where
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:
By Angle Measures:
The sum of the interior angles of any triangle always adds up to 180 degrees.
