1. The problem asks to identify types of angles marked in three different graphs involving parallel lines and transversals. 2. **Corresponding angles** are pairs of angles that are in the same relative position at each intersection where a transversal crosses parallel lines. 3. **Vertically opposite angles** are pairs of angles opposite each other when two lines intersect. They are always equal. 4. **Alternate interior angles** are pairs of angles on opposite sides of the transversal but inside the two parallel lines. 5. In the left graph, the two purple shaded angles are on alternate interior sides of the transversal, so they are **alternate interior angles**. 6. In the center graph, the two green shaded angles occupy the same relative position at each intersection (top-left of upper and lower lines), so they are **corresponding angles**. 7. In the right graph, the two pink shaded angles are opposite each other at the intersection of two lines, so they are **vertically opposite angles**. Final answer: The left graph shows alternate interior angles, the center graph shows corresponding angles, and the right graph shows vertically opposite angles.
