WebMay 8, 2024 · The trigonometric functions -- sine, cosine, and tangent -- are based on a right-angled triangle (a triangle containing an angle equal to 90 degrees). In math class, these trig functions are found using various trigonometric ratios comparing the length of the triangle's adjacent and opposite sides with that of the hypotenuse or with each other.

WebIn National 4 Maths Trigonometry is used to find the size of a missing side or angle in a right-angled triangle using the sine, cosine or tangent ratios WebTrigonometry. So far we have seen relationships between the angles of triangles (e.g. they always sum up to 180°) and relationships between the sides of triangles (e.g. Pythagoras). But there is nothing that connects the size of angles and sides. For example, if I know the three sides of a triangle, how do I find the size of its angles ...
