Bisect an Angle by Jonathan Garfield

This GeoGebra example demonstrates how to construct the bisector of an angle dynamically, showing the angle being divided into two equal parts. The core mathematical concept is the definition and property of an angle bisector, which splits an angle into two congruent angles. The construction uses the Ray command to create the two sides of the angle, the Angle command to mark and measure the angle α, and a text object (text1) to display the angle measure. Suitable for middle school geometry lessons to visualize angle bisectors, and also useful for high school review of geometric constructions, enhancing understanding of dynamic geometry tools.
