# What are the parts of trigonometry?

The main part of trigonometry is the study of triangles on spheres. Also, another part of trigonometry is the constant positive curvature.

### What is the difference between plane trigonometry and spherical trigonometry?

Trigonometry is the study of plane and spherical triangles. Plane trigonometry deals with 2 Dimensional triangles like the ones you would draw on a piece of paper. But, spherical trigonometry deals with circles and 3 Dimensional triangles. Plane trigonometry uses different numbers and equations than spherical trigonometry. There's plane trigonometry, where you work with triangles on a flat surface, then there's spherical trigonometry, where you work with triangles on a sphere.

### How is trigonometry ues today?

Trigonometry is used in the design and construction of buildings, cars, planes, and many other objects. Trigonometry is used in physics and engineering whenever forces, waves, fields, and vectors are involved. Trigonometry is used in music and acoustics to design speakers, instruments, and concert halls. Trigonometry is used to coordinate launches OS space shuttles. Trigonometry is used to navigate ships and planes. Nearly every part of modern life uses trigonometry in some way.
