How Do I Find The Area Of An Equilateral Triangle Using Its Formula
Let's look at the geometric characteristics of an equilateral triangle. But first, please review the definition of
Area Of Two-Dimensional Shapes, and
- An equilateral triangle has two unique features.
- The first unique feature - all three sides of the triangle
are exactly the same length. In this example sides A are of equal
- The second unique feature of an equilateral triangle
are the interior angles are exactly 60°. The sum of the interior angles is 180°.
- Special note, all sides of an Equilateral Triangle must be greater than zero.
Area Of An Equilateral Triangle Formula
Formula = (√3 ÷
4) × SideA2 =
Formula = √ 3 × 0.25 × SideA2 =
Formula = 1.73205080 × 0.25 × SideA2 =
Formula = 0.4330127 × A2
