Multiple Kosnita Menggunakan Circumcenter Dan Orthocenter Melalui Excenter

Special lines, such as angle bisectors, altitudes, medians, and perpendicular bisector can be constructed in a triangle. These special lines are concurrent with their corresponding concurrent points, and called incenter and excenter, orthocenter, centroid, and circumcenter. This thesis discusses how to construct the multiple Kosnita using circumcenter and orthocenter passing through excente…
