Dynamic Construction of the Incenter of a Triangle

2019-12-29 04:07
This interactive applet demonstrates the geometric construction and properties of the incenter of a triangle. By dragging the vertices, users can dynamically observe the intersection of the three angle bisectors (the incenter) and the inscribed circle tangent to all three sides. It provides a visual exploration of angle bisector theorems and incircle properties, ideal for teaching plane geometry.
