Answer 1

For the given figure:

According to the statements provided, we will name the lines that are parallel to each other:

1) ∠1 ≅ ∠3; The parallel lines are (c, d)

2) ∠6 ≅ ∠9; the parallel lines are (a, b)

3) ∠6 is supplementary to ∠10; the parallel lines are (a, b)

4) ∠1 ≅ ∠11: Not enough info

5) ∠5 is supplementary to ∠8; the parallel lines are (c, d)

6) ∠3 ≅ ∠11; The parallel lines are (a, b)

7) ∠1 ≅ ∠6; Not enough info

8) ∠1 ≅ ∠14: the parallel lines are (a, b)

9) ∠15 is supplementary to ∠16; Not enough info

10) ∠13 ≅ ∠15; the parallel lines are (c, d)
