Equilateral triangle - Wikipedia
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 side length. Its area is a quarter of the square root of three multiplied ...

ABC is an equilateral triangle since AB≅AC≅BC. An isosceles triangle has at least two equal sides, so an equilateral triangle is also an isosceles triangle. Angle measures An equilateral triangle is also called an equiangular triangle since its three angles are equal to 60°. In an isosceles triangle, the base angles are congruent.
Equilateral Triangle - GeeksforGeeks
An equilateral triangle is a type of triangle in which all three sides are equal in length and all three interior angles are equal. Since the sum of the interior angles of a triangle is 180°, each angle in an equilateral triangle measures 60°.
Equilateral Triangle -- from Wolfram MathWorld
An equilateral triangle is a triangle with all three sides of equal length a, corresponding to what could also be known as a "regular" triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal. An equilateral triangle also has three equal 60 degrees angles. The altitude h of an equilateral triangle is h=asin60 degrees ...

Equilateral triangle - Simple English Wikipedia, the free encyclopedia
Equilateral triangle In geometry, an equilateral triangle is a triangle where all three sides are the same length and all three angles are also the same and are each 60 °. If an altitude is drawn, it bisects the side to which it is drawn, in turn leaving two separate 30-60-90 triangles
