   Trigonometry is the study of lengths and angles in triangles. This section looks at trigonometry in right-angled triangles. In a right-angled triangle the side opposite the right angle is the hypotenuse, which is the longest side. † AC is the hypotenuse † AB is adjacent to angle A (•) † BC is opposite • Investigation • right-angled ...
