4 resourcesSine Rule, Cosine Rule and Area
Area = ½ab sin C, the cosine rule (a side or an angle), the sine rule, two-step problems (the angle not opposite a known side, or the side next to the angle), deciding whether it is the ambiguous case and why (including no…
🔗 MatchingProving the Sine Rule, Cosine Rule and Area Formula: Ordering
Put the steps of each proof in order: area = ½ab sin C, the sine rule and the cosine rule, each with its diagram. Any order where every step follows from the ones before it is accepted. Prints as a worksheet with answers.
