identify the type of pair of angles labeled as 1 and 2 in the figure.

a) vertical angles
b) linear pair
c) complementary angles
d) adjacent angles

Explanation:

A linear pair of angles is formed when two adjacent angles are supplementary (their sum is \(180^\circ\)) and they form a straight line. Angles 1 and 2 are adjacent, form a straight line, and their sum is \(180^\circ\), so they are a linear pair. Vertical angles are opposite and equal, complementary angles sum to \(90^\circ\), and adjacent angles just share a common side and vertex (but a linear pair is a specific type of adjacent supplementary angles here).

Answer:

B) Linear pair
