File:Equilateral triangle with height square root of 3.svg. Add languages. ... A 30-60-90 triangle embedded in an equilateral triangle with sides of length 2.
The triangle, viewed face-on, appears equilateral. In (4), the distances of P from lines BC , AC and AB are denoted by a ′ , b ′ and c ′ , respectively. For any line l = s + t n̂ in vector form ( n̂ is a unit vector) and a point p , the perpendicular distance from p to l is

For any interior point P, the sum of the lengths of the perpendiculars s + t + u equals the height of the equilateral triangle.. Viviani's theorem, named after Vincenzo Viviani, states that the sum of the shortest distances from any interior point to the sides of an equilateral triangle equals the length of the triangle's altitude.

An equilateral triangle is a triangle in which all three sides have the same length, and all three angles are equal. Because of these properties, the equilateral triangle is a regular polygon, occasionally known as the regular triangle. It is the special case of an isosceles triangle by modern definition, creating more special properties.
