    Another simple construction of the golden section in an isosceles triangle - Tran Quang Hung​

    Given an isosceles triangle, consider the circle with its top vertex as center and passing through the other two vertices. Using a symmedian, we construct a chord of the circle parallel to the base of the triangle to intersect the equal sides so that for each segment formed by three contiguous points is divided in the golden ratio.
