All right i’m just behind and so yea

1. 1 & 3, and 2 & 4.

2. 3 & 2

3. 1 & 4

4. 1 & 2 and 3 & 4.

5. 1 = 3 and 2 = 4

6.  congruent.

7.  supplementary.

8.  congruent.

9. supplementary.

10. congruent.

11. congruent.

Step-by-step explanation:

1. Two pairs of vertical angles are 1 & 3, and 2 & 4.

2. The alternate interior angles from the diagram are 3 & 2

3. 1 & 4 = the alternate exterior angles.

4. 1 & 2 and 3 & 4 are the two pairs of corresponding angles are.

5.  The pair of angles that are congruent are 1 = 3 and 2 = 4 {Since, they are vertically opposite angles.}

6. Alternate interior angles = congruent.

7. Linear pairs are supplementary.

8. Corresponding angles = congruent.

9. Same side interior angles are supplementary.

10. Vertical angles are congruent.

11. Alternate exterior angles = congruent. (Answer)
