Angles

This is just here so I don’t forget ;)
(small characters here refer to angles, capitals to lengths of sides)

A triangle without a 90 degree angle

Python equivalents of the above math are for instance (untested):

A = math.sin(a) / (math.sin(b)/B)

B = math.sin(b) / (math.sin(c)/C)

C = math.sin(c) / (math.sin(a)/A)

A triangle with a single 90 degree angle (a in this case)

Python equivalents of the above math are for instance:

c = math.asin(C/A)

c = math.acos(A/C)

c = math.atan(C/B)

A = math.sqrt(B*B+C*C)
