Key Stage 3 Geometry & Measures & GCSE— using trigonometric ratios in right-angled triangles to solve problems.

CCSS HSF-TF.A.3
Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosine, and tangent for π–𝘹, π+𝘹, and 2π–𝘹 in terms of their values for 𝘹, where 𝘹 is any real number.
CCSS HSG-SRT.C.7
Explain and use the relationship between the sine and cosine of complementary angles.

CCSS HSG-SRT.C.8
Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
