Why using area and perimeter rules doesn't give the right answer?

I have created yet another sometime pass solution which got past random testing on the first try, but will fail a tests such as:

33 40 'Upstream 0'
Expected: 0.83, instead got: 0.82

Random testing should be strengthened to guarantee such tests appear.

Please, check if input '39.63° S, 100.00° W', '23.13° S, 35.97 W' should return 3300KM or something different because I didn't pass this test in the first attempt. It showed that the correct result was about 6100KM.

I think at least one more basic tests should be added because with only two examples we cannot be sure of what we're supposed to do.

No tests with superfluous character at the beginning/end of the string.

in python at least, the random tests are sending inputs that aren't triangles... (like 6,55,93)

From random tests:

83X²+21x+21=21
Expected: '\'No real roots exist!\'', instead got: '[-0.25, 0]'

Also as mentioned below, sometimes the test generates a quadratic coefficient of 0.

As mentioned below, a duplicate.
