Right-angled triangles
Understand and apply the sine, cosine, and tangent ratios for acute angles in right-angled triangles, with angles provided in degrees and answers expressed in degrees to one decimal place. Solve two-dimensional problems using Pythagoras' theorem and trigonometry, which may involve bearings. Recognize that the shortest distance from a point to a line is the perpendicular distance. Perform calculations related to angles of elevation and depression.
