Final answer:
To prove p || q, we need to show that the angles <1 and <2 are parallel. Since the given statement is <1 - <2, we can rewrite it as <1 = <2. Two congruent angles are always parallel, so we can conclude that p || q.
Step-by-step explanation:
The given argument pattern is:
1. P > Q
2. Q
3. P
To prove that p || q, we need to show that the angles <1 and <2 are parallel.
Since the given statement is <1 - <2, we can rewrite it as <1 = <2. This means that <1 and <2 are congruent angles.
Two congruent angles are always parallel, so we can conclude that p || q.
