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 primarily with angles and triangles; in particular, it defines and uses the relationships and ratios between angles and sides in triangles.The primary application is thus solving triangles, precisely right triangles Leņķim A pretkatete - CB , piekatete CA.
