Internal and External Angle Bisectors with Locus Circle

2014-10-05 01:31
This GeoGebra example demonstrates the geometric properties of internal and external angle bisectors of a triangle and their locus. By constructing the internal and external angle bisectors, it shows that the locus of the angle bisector point (point C) traces a circle as parameters vary. The construction involves polygons, segments, angles, rays, and conditional commands, utilizing dynamic geometr
