# Ce este trigonometria?

> Descoperă cum leagă trigonometria unghiurile și laturile triunghiurilor.

## Trigonometria

Trigonometria studiază relațiile dintre unghiuri și laturi, în special în triunghiurile dreptunghice.

## Funcții

Sinusul, cosinusul și tangenta permit calcularea laturilor și unghiurilor necunoscute.
