This section looks at the Sine Law and Cosine Law. The Sine Rule The Law of Sines (sine rule) is an important rule relating the sides and angles ofanytriangle (it doesn'thaveto be right-angled!): If a, b and c are the lengths of the sides opposite the angles A, B and C in ...
the Cosine Rule The Sine Rule Method 1. Use either the right, or left hand equation. 2. You are given 3 quantities and required to work out the 4 th. Manipulating the ratio- Take two ratios, cross multiply and rearrange to put the required quantity as the subject of the equation. ...
and angles in non-right angled triangles we can use one or both of 2 rules: the sine rule The cosine rule The next few slides prove the sine rule. The cosine rule is on the next presentation.The Sine RuleABC is a scalene triangle a, b and c are the sides opposite angles A, B ...
