Radians in Unit Circle by miriam.spano
Loading the math board and drawing, please wait…
This example demonstrates the concept of radians in a unit circle. By constructing circles, segments, and rotating objects, it visually illustrates the relationship between radians and degrees. It uses commands such as Line, Circle, OrthogonalLine, Intersect, Segment, Rotate, Angle, CircleArc, Vector, Translate, Mirror, Point, Polygon, Ray. Suitable for high school math education, helping students understand the radian system.
