Master Trigonometry to enhance academic achievement and embed foundational skills for Year 11.
Year 10 Trigonometry covers the fundamental principles of measurement with triangles as described in the Australian curriculum. In Trigonometry, students become better able to select and apply rules and processes to find unknown angles and side lengths. These skills are fundamental to solve problems involving bearings and angles of elevation and depression.
This learning program is made up of the following 5 topics, broken down into 15 concepts.
Review Pythagoras theorem
Apply Pythagoras' Theorem to 3D problems
Define the sine, cosine and tangent ratios for angles in right-angled triangles
Identify the hypotenuse, adjacent sides and opposite sides on a right angles triangle
