PENGEMBANGAN INNER DAN OUTER VAN AUBEL PADA SEGIEMPAT NON KONVEKS DENGAN SETENGAH LINGKARAN
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
of opposite semicircular arcs are connected, then two lines are equal in length
and intersect perpendicularly.
Keywords: Van Aubel’s theorem, non-convex, cosine rule, congruence
