First, a complementary angle are two angles that add up to 90. while supplementary add up to 180.
Complementary angles; 1 & 2, 3 & 4, 9 & 10, 11 & 12. (these all make one line which equals 180.)
Supplementary angles; 7 & 8, 5 & 7, 6 & 5, 8 & 6. (these all make up a 90 degree angle.)
Hope this helps. <3
