Cosine Rule - Know 2 sides, and the angle in between. You want the missing side. a² = b² + c² - 2bcCosA Cosine Rule - Know 3 sides. You want an angle. Cos A = (b² + c² - a²) ÷ 2bc Sine Rule - Know 2 angles and a side. You want the missing side. (a ÷ SinA) = (b ÷ SinB) = (c ÷ SinC) Sine Rule - Know 2 sides and an angle. You want a missing angle. (Sin A ÷ a) = (Sin B ÷ b) = (Sin C ÷ c) Midpoint of a line segment on a circle. ( (x₁ + x₂) ÷ 2 ) , ( ...
