<p>The Equilateral Triangle<a>calculator</a>is a tool designed for calculating the properties<a>of</a>an equilateral triangle. An equilateral triangle is a two-dimensional shape where all three sides are equal in length, and all three angles are equal, each measuring 60 degrees. The<a>term</a>"equilateral" comes from the Latin words "aequus" meaning "equal" and "latus" meaning "side".</p>
