Gosh. You drew it very well, so I can tell you that based on your drawing, if it looks the same, it probably is congruent. For a list though:
1, 3, 5, 7, 9, 11, 13, 15 are all congruent by vertical angles, corresponding angles, alternate interior angles, and alternate exterior angles
2, 4, 6, 8, 10, 12, 14, 16 are all congruent by vertical angles, corresponding angles, alternate interior angles, and alternate exterior angles
1 and 2 are supplementary
1 and 4 are supplementary
3 and 2 are supplementary
3 and 4 are supplementary
5 and 6 are supplementary
5 and 8 are supplementary
7 and 6 are supplementary
7 and 8 are supplementary
1 and 8 are supplementary
2 and 7 are supplementary
4 and 5 are supplementary
3 and 6 are supplementary
And on and on and on...
