Once you know these problems involving non-right angled triangles can be solved. Use of the sine and cosine rule leads into more senior levels of maths. Learning Intention Using the Sine Rule to find unknown sides and angles Using the Cosine Rule to find unknown sides and angles.Combining trigonometry skills to solve problems. Using the sine and cosine rule to calculate area. Key Vocabulary Terms anglescosinecosine ruleright angled trianglesinesine ruletangenttriangle Literacy Numeracy Information and communication technology capability Critical and creative thinking Personal and social capability Ethical behaviour Intercultural understanding Aboriginal and Torres Strait Islander histories and cultures Asia and Australia’s engagement with Asia Sustainability Select from the options below to edit settings for this learning bite.
