1. The problem asks to identify the types of angles marked in three different diagrams involving parallel lines and a transversal. 2. For (a), the two green angles are on opposite sides of the transversal and between the parallel lines. This matches the definition of **Alternate Interior Angles**. 3. For (b), the two blue angles are on opposite sides of the transversal but outside the parallel lines. These are called **Alternate Exterior Angles**. 4. For (c), the two purple angles are on the same side of the transversal, with one above and one below the parallel lines. These are **Corresponding Angles**. 5. Vertically opposite angles are not shown in these diagrams as they occur where two lines intersect, not necessarily involving parallel lines and a transversal. Final answers: a) Alternate Interior Angles b) Alternate Exterior Angles c) Corresponding Angles
