Problem by Debra Schneider Source: Open Middle

Use the input boxes to create a pair of supplementary angles that meets the criteria explained in the problem above.

What two angle measures did you find to solve the problem above? Can you find another pair where the difference between the two measures is SMALLER?

NEXT TASK: Create a pair of supplementary angles using NON-REPEATED DIGITS whose DIFFERENCE is AS LARGE AS POSSIBLE.

What two angle measures did you find to solve the problem above? Can you find another pair where the difference between the two measures is GREATER?
