Question

name the angle pair

Explanation:

Adjacent angles are two angles that share a common vertex and a common side but do not overlap. In the given diagram, angles \( \angle 1\) and \( \angle 2\) share vertex \( B\) and side \( BD\) (or \( BC\) - depending on the exact structure, but the key is the common vertex and side). They meet the definition of adjacent angles. Supplementary angles sum to \( 180^{\circ}\), vertical angles are opposite each other when two lines intersect, and complementary angles sum to \( 90^{\circ}\). None of these other definitions fit the given angle - pair as well as the adjacent - angle definition.

Answer:

Adjacent
