Final answer:
The relationships between ∠1 and ∠2 can be summarized as: acute angles, right angles, complementary angles, or supplementary angles.
Step-by-step explanation:
When analyzing the relationships between angles, we can check for several possibilities. Let's consider ∠1 and ∠2:
If ∠1 and ∠2 are both acute angles (less than 90 degrees), they are both less than 180 degrees and cannot be supplementary angles.
If ∠1 and ∠2 are both right angles (equal to 90 degrees), they are congruent angles.
If ∠1 and ∠2 are complementary angles (two angles that add up to 90 degrees), they are not congruent angles.
If ∠1 and ∠2 are supplementary angles (two angles that add up to 180 degrees), they are not congruent angles.
Therefore, the relationships between ∠1 and ∠2 can be summarized as follows: they can be both acute angles, they can be both right angles, they can be complementary angles, and they can be supplementary angles
