dc.description.abstractThe goal of this article is to formalize some theorems that are in the [17] on the web. These are elementary theorems included in every handbook of Euclidean geometry and trigonometry: the law of cosines, the Heron’s formula, the isosceles triangle theorem, the intersecting chords theorem and the Ptolemy’s theorem.pl
