Answer:
- Corresponding Angle Postulate
- Corresponding Angle Postulate
- Reflexive Property
- Similar
Explanation:
The pairs of angles referenced in statements 1 and 2 are "corresponding" angles, so the Corresponding Angle Postulate applies.
The Reflexive Property is what says something is the same as itself. This is used in statement 3.
The upshot of the AA Similarity postulate is to say triangles are similar (as in statement 4).
