The diagram shows two sets of parallel lines: $m \parallel n$ and $j \parallel k$, forming several angles labeled from 1 to 8.

This is a typical problem involving transversal lines and angle relationships, such as corresponding angles, alternate interior angles, and consecutive interior angles.

Given the information, here are key points to consider:

• Corresponding angles: These are angles that are in the same position at each intersection. For example, angle 1 and angle 5 are corresponding angles.
• Alternate interior angles: These are angles that lie between the two parallel lines on opposite sides of the transversal. For example, angle 3 and angle 6 are alternate interior angles.
• Consecutive interior angles: These are angles on the same side of the transversal and inside the parallel lines. For example, angle 3 and angle 5 are consecutive interior angles.

Now, the question asks, "Which statement is true?" Based on the diagram, several relationships are possible, such as:

1. Corresponding angles are congruent.
2. Alternate interior angles are congruent.
3. Consecutive interior angles are supplementary.

If you have a list of statements to choose from, these relationships can help you determine which one is true. Could you provide the possible statements, or would you like to explore these angle relationships further?

Here are five related questions to deepen your understanding:

1. What are corresponding angles, and why are they congruent when parallel lines are involved?
2. How can you identify alternate interior angles in different diagrams?
3. Why are consecutive interior angles supplementary when dealing with parallel lines?
4. What happens to these angle relationships if the lines are not parallel?
5. How can you use these angle relationships to solve problems involving parallel lines and transversals?

Tip: When working with parallel lines cut by a transversal, always look for corresponding and alternate interior angles to simplify solving for unknown angles.
