The image shows a diagram with two intersecting transversals (labeled $a$ and $b$) and two parallel lines (labeled $s$ and $t$). There are numbers placed at the intersections between these lines, forming different angles.

You are likely asked to identify the specific types of angles in this diagram. Common angle relationships in such diagrams include:

1. Corresponding angles: Angles in the same relative position at each intersection of the transversal with the parallel lines.
2. Alternate interior angles: Angles located between the two parallel lines, on opposite sides of the transversal.
3. Alternate exterior angles: Angles located outside the parallel lines, on opposite sides of the transversal.
4. Same-side interior angles: Angles located between the parallel lines on the same side of the transversal.

Would you like me to help you identify the specific angle types for questions 7-10? Feel free to provide more details on the questions if needed.

Here are 5 related questions to explore further:

1. Can you identify which angles in the diagram are alternate interior angles?
2. Which angles in the diagram are corresponding angles?
3. What is the relationship between same-side interior angles when the lines are parallel?
4. How can you prove that $s$ and $t$ are parallel using the angles formed by the transversals?
5. How do alternate exterior angles compare in measure when lines are parallel?

Tip: Remember, when two lines are parallel, corresponding angles are always congruent.
