I took complements of the test case polar angles in order to agree with customary definitions of polar angle.

I agree. Polar angles are, by convention, measured from the pole, but in this problem you have to consider them to be measure from the equator if you wish to agree with the test cases.

Fabricio Castro on 3 Nov 2020

I think considering polar angles measured from pole or from equator does not affect the result in this problem. But if you consider polar angle of the first point measured from pole and the polar angle of the second one from equator it will produce misleading solutions. So, you need to stabilish the same convention for both points.
