Final answer:
To prove that angle 1 (∠1) is congruent to angle 2 (∠2), we can use the given information and the transitive property of congruence.
Step-by-step explanation:
To prove that angle 1 (∠1) is congruent to angle 2 (∠2), we need to use the given information and complete the missing parts of the paragraph proof. Let's start with the given statements:
1. Line 1 is parallel to line m.
2. Angle 1 (∠1) is equal to angle 3 (∠3).
To prove that ∠1 ≅ ∠2, we can use the transitive property of congruence. Since ∠1 ≅ ∠3 (given), and ∠3 ≅ ∠2 (by the transitive property), we can conclude that ∠1 ≅ ∠2.
