Find unknown side lengths, angles and area given some known values.

SAAA

Find side lengths and area given 1 side length and 3 angles.

Input: a, α, β, γ

• a is the side length opposite angle α
• α is the angle opposite side a
• β is the angle opposite side b
• γ is the angle opposite side c

α + β + γ = 180°

Output: b, c, A

• b is the side length opposite angle β
• c is the side length opposite angle γ
• A is the area

Example

SAS

Find side lengths, angles and area given 2 side lengths and 1 angle between the known sides.

Input: a, b, γ

• a is the side length opposite angle α
• b is the side length opposite angle β
• γ is the angle opposite side c

Output: c, α, β, A

• c is the side length opposite angle γ
• α is the angle opposite side a
• β is the angle opposite side b
• A is the area

Example

SSA

Find side lengths, angles and area given 2 side lengths and the angle opposite a.

Input: a, b, α, dβ

• a is the side length opposite angle α
• b is the side length opposite angle β
• α is the angle opposite side a
• dβ is the range of the angle opposite b (usually either acute or obtuse)

Output: β, γ, c, A

• β is the angle opposite side b
• γ is the angle opposite side c
• c is the side length opposite angle γ
• A is the area

Example

SSS
