The rules of trigonometry for triangles primarily involve relationships between the sides and angles. For right-angled triangles, the basic trigonometric ratios are used: = OppositeHypotenuse = AdjacentHypotenuse = OppositeAdjacent For any triangle (not just right-angled), the following rules apply: The Sine Rule relates the ratio of a side length to the sine of its opposite angle: (a)/( A) = (b)/( B) = (c)/( C) The Cosine Rule is used to find a side when two sides and the included angle are known, or to find an angle when all three sides are known: a^2 = b^2 + c^2 - 2bc A The Area Rule allows you to calculate the area of a triangle using two sides and the included angle: Area = (1)/(2)ab C That's 2 down. 3 left today — send the next one.
