PENGEMBANGAN INNER DAN OUTER VAN AUBEL PADA SEGIEMPAT NON KONVEKS DENGAN SETE…

This final project discusses the development of Van Aubel’s theorem on nonconvex quadrilaterals with semicircles. The process of proving this theorem uses the cosine rule, and the congruence and congruence approaches. In a nonconvex quadrilateral, each side is constructed as a semicircle, with the diameter of each semicircle being a side of the non-convex quadrilateral. If the midpoints …
