Question

name the relationship between $angle a$ and $angle b$. select all that apply.
vertical
complementary
supplementary
linear pair
adjacent

Explanation:

• Vertical angles are opposite each other formed by intersecting lines; ∠a and ∠b do not fit this.
• Complementary angles sum to 90°, which is not indicated here.
• Supplementary angles sum to 180°, which is not shown here.
• A linear pair are adjacent angles forming a straight line (sum to 180°), which is not the case here.
• Adjacent angles share a common vertex and side, no overlapping interior; ∠a and ∠b meet this criteria.

Answer:

Adjacent
