Equilateral triangle - Wikipedia
Equilateral triangle ... An equilateral triangle is a triangle with three sides of equal length and three equal angles. It is a regular polygon, occasionally known as the regular triangle. It is a special case of an isosceles triangle by modern definition. Its internal angle is 60° in degree or π /3 in radian. Its perimeter is three times the ...
