What is trigonometry?
Trigonometry is a branch of mathematics. The word itself comes from the Greek trigōnon (which means "triangle") and metron ("measure"). As the name suggests, trigonometry deals mostly with angles and triangles; in particular, it's defining and using the relationships and ratios between angles and sides in triangles. The primary application is thus solving triangles, specifically right triangles, but also any other type of triangle you like.
