What is inscribed circle and how its radius calculated for an equilateral triangle ?

The radius of the inscribed circle of an isosceles triangle is the length of the radius of the circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. In an equilateral triangle, all three sides are equal and all the angles measure 60 degrees. The radius of the inscribed circle is calculated by the formula R = √3a /6 where R is the radius of the inscribed circle and is the length of the side of an inscribed circle.
