Pengembangan Mixtilinear Incircle Pada Segi Empat Siklik
ABSTRACT
This final project discusses the development of the concept of a mixtilinear incircles
in a cyclic quadrilateral. The development carried out is to show the
various relationships formed between the mixtilinear incircles radii that can
be constructed on the cyclic quadrilateral. In any triangle ABC, three different
mixtilinear incircles can be constructed. In this final project, point D is
constructed on the circumcircle of △ABC in order to obtain a cyclic quadrilateral
ABCD, so that mixtilinear incircles can be formed. By formulating
various mixtilinear incircles radii, it is shown that the ratio of the product of
the mixtilinear incircles radii of the adjacent triangle is equal to the ratio of the
diagonals of the cyclic quadrilateral.
