Proof of the Law of Sines
2016-02-28 20:02
This applet visually demonstrates the geometric proof of the Law of Sines. Using polygon and angle tools, it constructs auxiliary elements in a triangle to derive the proportional relationship between side lengths and the sines of their opposite angles (a/sinα = b/sinβ = c/sinγ) through area relationships. Ideal for teaching and intuitive understanding of trigonometry and solving triangles in midd
