WebTrigonometry involves calculating angles and sides in triangles. Labelling the sides. The three sides of a right-angled triangle have special names. The hypotenuse (\(h\)) is the longest side. WebThe purpose of trigonometry is to find missing lengths and angles. For the time being, we will simply consider trigonometry in right-angled triangles. However, later on in another article, we will consider trigonometry in triangles that are not necessarily right-angled using what is known as the sine and cosine rule. Trigonometric Ratios
Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths.
