Tests are passable in C and C++ without even declaring floats

Yes thank you. That test is useless or should be True. You can make the angle between 1 and 2 wider enough until line 3 builds a triangle. This kata is not well built. The only way to solve this kata is to modify the solution until you trick all the tests.

(In this case, all triangles must have surface greater than 0 to be accepted).

they pass because the test only inlude even diferents between the percentages, wich made the division exact, causing zero decimals in the solution, making it irrelevant if you use float or int. The easy solution to fix it, is to return a float.

It is perfectly possible: 68 guys passed the kata...

you can build a triangle with 3 2 1

c should be remove from the lenguages abiable, due to the inability to pass from a float to an int.

I really did it the hard way, then i saw the solutions(mindBlown).
Thanks to the author, learnt some Array methods because of you, nice Kata.

It should be helpful if you state which language and show your code (mark your post as having spoiler content). Otherwise there is nothing we can do to help you.

dosen't work fo me
