Dynamic Investigation of Triangles Inscribed in a Circle, Which Tend to an Equilateral Triangle

International Journal of Mathematical Education in Science and Technology, v48 n1 p149-161 2017
We present a geometrical investigation of the process of creating an infinite sequence of triangles inscribed in a circle, whose areas, perimeters and lengths of radii of the inscribed circles tend to a limit in a monotonous manner. First, using geometrical software, we investigate four theorems that represent interesting geometrical properties, after which we present formal proofs that rest on a combination between different fields of mathematics: trigonometry, algebra and geometry, and the use of the concept of standard deviation that is taken from statistics.
