This GeoGebra applet visually demonstrates the definition of the radian measure and its conversion to degrees. By dynamically showing the ratio of arc length to radius, it helps users deeply understand the geometric meaning of radians. The interface includes interactive circles, arcs, rotation angles, and a conversion table for degrees and radians, making it ideal for beginners in trigonometry.
