The line r is the transversal and ∠1 and ∠2 are linear pairs.
<h3 /><h3>Angles formed when a transversal cuts parallel lines</h3>
When a transversal cuts parallel lines , angles formed includes corresponding angles, alternates angles, linear pair angles etc.
Therefore, p and q are the parallel lines.
The transversal is r.
The transversal r, cuts the parallel lines p and q.
Therefore, line r is the transversal and ∠1 and ∠2 are linear pairs.
