Right-angled triangles past paper questions

O Level Mathematics 4024 · Trigonometry. 1 Know and use the sine, cosine and tangent ratios for acute angles in calculations involving sides and angles of a right-angled triangle. 2 Solve problems in two dimensions using Pythagoras’ theorem and trigonometry. 3 Know that the perpendicular distance from a point to a line is the shortest distance to the line. 4 Carry out calculations involving angles of elevation and depression. Angles will be given in degrees and answers should be written in degrees, with decimals correct to one decimal place. Knowledge of bearings may be required.
