Solution Steps

Step 1: Identify the Parallel Lines and Transversal

Given parallel lines \( l \) and \( m \), and a transversal intersecting them, we need to identify the angles formed by the transversal.

Step 2: Determine Corresponding Angles

When a transversal intersects two parallel lines, corresponding angles are congruent. In this diagram, angles 2 and 5 are corresponding angles.

Step 3: Select the Correct Answer

From the given choices, the pair of angles that must be congruent are \(\angle 2\) and \(\angle 5\).

Final Answer

J. \(\angle 2\) and \(\angle 5\)
