Law of Sines

The Law of Sines is defined as:

\[ \frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)} = 2R \]

Where:

  • a, b, c are the lengths of the sides of the triangle
  • A, B, C are the angles opposite to sides a, b, c respectively
  • R is the radius of the circumscribed circle

Properties:

  • Works for any triangle
  • Relates sides and angles of a triangle
  • Can be used to find missing sides or angles
  • Useful for solving ambiguous cases

Applications:

  • Navigation and surveying
  • Physics (wave motion)
  • Engineering (structural analysis)
  • Astronomy
  • Computer graphics

Common Cases:

  • Acute triangles
  • Right triangles
  • Obtuse triangles
  • Ambiguous case (SSA)
