[[Image:Triangle.Equilateral.svg|right]]An '''equilateral [[triangle]]''' has, by definition, three sides that are equal in length, or so says [[liberal]] mathematicians (See [[liberal bias]]).  

In classical [[geometry]] it can easily be proved that an equilateral triangle is also ''equiangular,'' that is each of its three angles is equal; since another theorem states that the three angles of a triangle total 180°, each of its angle is 60° each.
