Let the sides of the equilateral triangle be 2 units. Then the altitude drawn from any corner onto the opposite side will be 3^0.5 units. The centre of the incircle will lie on this altitude at a distance of one-third of the altitude from the base. Thus the radius will be 1/3 of 3^0.5 or 0.577 units The circle is inscribed in the triangle, so the two radii, OE and OD, are perpendicular to the sides of the triangle (AB and BC), and are equal to each other. BE=BD, using the Two Tangent theorem. BEOD is thus a kite, and we can use the kite properties to show that ΔBOD is a 30-60-90 triangle Relationship of the medians, heights, angle bisectors and perpendicular bisectors with the circumscribed circle's radius and inscribed circle's radius of a regular triangle.
