This little package applies the law of sines or cosines to find all the sides and angles of a triangle, if you know some of the sides and/or angles.

The main function defined by this package is solve(…). Simple example:

from math import pi
from trianglesolver import solve
a,b,c,A,B,C = solve(b=7.6, c=8.3, A=pi/3)

Following the usual convention, lower-case letters are side lengths and capital letters are angles. Corresponding letters are opposite each other, e.g. side b is opposite angle B.

All angles are in radians! However, you can use the degree constant to convert:

from trianglesolver import solve, degree
a,b,c,A,B,C = solve(b=7, A=5*degree, B=70*degree)
print(C / degree)
