A novel Constructive Geometric Approximation of the Ellipse Perimeter Using Isosceles Trapezoids

We present a novel geometric method for approximating the perimeter of an ellipse by decomposing it into radial sectors and rearranging them into an isosceles trapezoid. This approach provides a constructible and intuitive alternative to classical analytic approximations such as those by Ramanujan.
