It is also called the cosine rule. If ABC is a triangle, then as per the statement of cosine law, we have: a2 = b2 + c2 – 2bc cos α, where a,b, and c are the sides of triangle and α is the angle between sides b and c.

WebProof of the extended Sine Rule. To prove this theorem, we need the properties of inscribed angles. An inscribed angle is an angle with a vertex on the circle and sides crossing this circle. Inscribed angles resting on the same arc are equal. An inscribed angle resting on a semicircle is right. The sum of the opposite angles of a quadrilateral ... Webthe sine rule or law of sines is the following identity: \frac { a} { \sin (A)} = \frac {b} {\sin (B)} = \frac {c} {\sin (C)}. sin(A)a = sin(B)b = sin(C)c. We will prove the first identity. \frac { a} …
