Three Excircles of a Triangle
2019-12-29 05:13
This applet demonstrates the construction of the three excircles of a triangle. An excircle is tangent to one side and the extensions of the other two. By constructing angle bisectors and perpendicular lines, the excenters are found and the circles are drawn. It visually illustrates the geometric properties of excircles and their relationships with the triangle's sides.
