Geometric Construction of the Equiangular Point in a Quadrilateral
2013-08-12 07:07
This GeoGebra example demonstrates how to construct an equiangular point P on the side AB of an arbitrary quadrilateral ABCD such that ∠ADP = ∠BCP. The construction steps include: drawing circles centered at A and B with radii AD and BD respectively to find intersection E, extending BC and EA to intersect at F, constructing the circumcircle of △ECF, and finding its intersection with AB as point P.
