Question

An equilateral triangle of side 20cm is inscribed in a circle. Calculate the distance of a side of the triangle from the center of the circle.

Answer 1

the center of the triangle is 2/3 of the distance from a vertex to the opposite side (2/3 of the height of the triangle)

so the distance from the center of the circle to a side of the triangle is 1/3 the height of the triangle
