TRIGONOMETRY

TRIGONOMETRY

1. Derivation of the Law of Sines:

   • calculate side or angle lengths of right triangles,using sine, cosine, or tangent
   • Triangles that do not have a right angle are called oblique triangles.

2. “solve the triangle

   • find all angle and side lengths.
   • to prove triangle congruencies

3. Triangle types

   • SSS
   • AAS
   • SSA
   • ASA
   • SAS

4. Area of an oblique triangle

   • The formula for the area of a triangle from Geometry is
     • where b = base length and h = height
