Transcript text: 6. Given parallel lines $l$ and $m$, which of the following choices lists a pair of angles that must be congruent?
F. $\angle 1$ and $\angle 2$
G. $\angle 1$ and $\angle 3$
H. $\angle 2$ and $\angle 3$
(J.) $\angle 2$ and $\angle 5$
K. $\angle 3$ and $\angle 5$
Solution
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 \(\angle 5\).
