Equilateral Triangle is a three sided two dimensional (2D) geometric figure. All the sides are equal in length and all the three inner angles are 60 degrees each.

Heightis the perpendicular drawn from the one vertex of the triangle to the opposite side of the triangle. This line always bisects the opposite side. Also, in case of an equilateral triangle, this is always equal whatever vertex you choose.

Areaof a triangle is calculated by the formula base * height / 2. In the case of an equilateral triangle, the base is the side (which are all equal)


AreaArea of a Equilateral Triangle is claculated by the formula: √ 3 * (Side² / 4)

PerimeterThis is calculated by the formula: 3 * Side

HeightHeight of the Equilateral Triangle is √ 3 * (Side / 2)
