2 Law of Sines

3 Non Right Triangles How is a triangle classified if none of the angles are 90? Oblique Labeling Oblique Triangles To solve oblique triangles? Find ALL side lengths and angle measures γ b a β α c

4 Solving Oblique Triangles
To solve we will need to know one of the following cases 1 side and 2 angles (SAA or ASA) 2 sides and the angle opposite one of them (SSA) 2 sides and the included angle (SAS) 3 sides (SSS) To use 1 or 2 we must use law of sines…

5 Law of Sines For a triangle with sides a, b, c and opposite angles α, β, γ, respectively, Remember:
