Trigonometry

What are we learning?

• Explore ratio in similar right-angled triangles

• Work fluently with the hypotenuse, opposite and adjacent sides

• Use the tangent ratio to find missing side lengths

• Use the sine and cosine ratio to find missing side lengths

• Use the sine, cosine and tangent to find missing side lengths

• Use the sine, cosine and tangent to find missing angles

• Calculate sides in right-angled triangles using Pythagoras’ Theorem (R)

• Select the appropriate method to solve right-angled triangle problems

• Work with key angles in right-angled triangles
