SOLUTION: Can someone help me on this problem? I have two parallel lines, I have a line going down the middle at a slant. On the top line I have a in the left hand corner and b on the

If you have this

          \
           \
   _________\_____________________
             \
              \
               \
       _________\_________________
                 \56°
                  \
                   \

Then its opposite angle is also 56°

          \
           \
   _________\_____________________
             \
              \
               \
       _____56°_\_________________
                 \56°
                  \
                   \

The opposite interior angles and exterior angles 
to the 56° angles are also 56° 


          \
           \
   _____56°_\_____________________
             \56°
              \
               \
       _____56°_\_________________
                 \56°
                  \
                   \

The other angles are supplementary to 56°, that is
they are found by subtracting 56° from 180°.

180° - 56° = 124°

          \
           \
   _____56°_\124°______________
         124°\56°
              \
               \
       _____56°_\124°_________________
             124°\56°
                  \
                   \
