1. The problem asks: What kind of angles are angles $a$ and $b$? 2. To determine the type of angles $a$ and $b$, we need more information about their relationship or measurements. 3. Common types of angle pairs include: - Complementary angles: sum to $90^\circ$ - Supplementary angles: sum to $180^\circ$ - Adjacent angles: share a common side and vertex - Vertical (opposite) angles: formed by two intersecting lines and are equal 4. Without additional context or a diagram, we cannot definitively classify angles $a$ and $b$. 5. Please provide more details or a diagram to identify the angle types.
