Sine Theorem
|
A theorem that shows the relationship between the angles and sides of a triangle. If the vertices of a triangle on a plane are A, B, and C, and the opposite sides are a , b , and c , then a/sinA = b/sinB = c/sinC = 2R ( R is the radius of the circumscribed circle). This is the sine law. Source: About Shogakukan Digital Daijisen Information | Legend |
