Add some tests for the functions.

Please rename the file to PythagoreanTheorem.

calcAdjacent and calcBase are practically the same function (a = sqrt(c2 - b2) and b = sqrt(c2 - a2)) - deduplicate them. Order shouldn't matter for a and b (adjacent vs. base).

You've got two tests both for adjacent & base calculation. Please merge them in a single function.

Looks good enough (would perhaps rename calcOtherSides to calcOtherSide since it calculates one other side).

Please use pythagorean triplets as tests. Your current tests are invalid.
