Law of Sines and Its Geometric Construction

2014-09-22 06:46

This GeoGebra applet demonstrates the geometric meaning and construction of the Law of Sines (a/sinA = b/sinB = c/sinC = 2R). By constructing a triangle and its circumscribed circle, it visually illustrates that the ratio of a side length to the sine of its opposite angle equals the diameter of the circumcircle. Featuring dynamic interactions with angles, segments, and circumcircle arcs, it helps
