Trigonometry is a word with Greek origins, from 'trig?non' meaning triangle, and 'metron' meaning measure. The subject is much as the name suggests, a branch of the broader subject of mathematics that looks at the relationships between the lengths of the sides of triangles and the angles between the sides. It is a complex subject that can lead students to a great deal of careers options including surveying, astronomy and engineering.
