Riješila sam zadatak https://brilliant.org/problems/hit-for-the-cycle/ na Brilliant org. pa mi pade na pamet da GeoGebra to može bez problema. Originani tekst zadatka: Suppose ABCD is a cyclic quadrilateral with side AD being a diameter of length d, sides AB and BC both having length a and side CD having length b such that a, b, d are all positive integers with a ≠ b.
Determine the minimum possible perimeter of ABCD.
