Copy of The Law of Sines - Lesson+Practice
The law of sines (or sine rule) relates the lengths of the sides of a triangle with the sines of its angles.
The apple below allows you to discover this useful law (Theorem), learn how it is obtained (Proof) and interact with a dynamic triangle (Explore!) to become familiar with this concept.
Solving a triangle means finding missing sides and angles - Let's solve one.
About the triangle in the app above, we know that , and . Solve the triangle.
