  1. Add in same variation to inscribed angles 2+3

    benkomalo committed Nov 7, 2011
    This does the same changes as was done to inscribed_angles_1 where the
    inscribed angle is given, and the central angle is asked for.
    
    There is still some code duplication here that can be cleaned up.
  2. Add in some variables to inscribed angles.

    benkomalo committed Nov 7, 2011
    This changes things up so that sometimes the inscribed angle is given,
    and the central angle is asked.

  1. Congruency postulates: take 2

    beneater committed Nov 1, 2011
  2. Fix couple floating point precision issues

    Danny Su committed Nov 1, 2011
    The root cause of exercises not accepting correct answers is due to
    floating point precision on some platforms.
    
    For issue 5198, the issue is due to the solution calculated is actually
    4599.999999999. This only repros on the specific Firefox version on Mac.
    The same version on Windows doesn't repro. The dividing decimals 2
    exercise expects the answer to be integers so fixing the issue by
    calling Math.round().
    
    For issue 4865, the issue is likely due to the same thing. The answer
    must be an integer, so also fixing the issue by calling Math.round().
