Question Analysis

This question involves the concepts of vertical angles and linear pairs.

Key Concept Explanation

Vertical angles: Formed when two lines intersect, they are opposite each other and have equal measures.

Linear pair: A pair of adjacent angles that share a common side and whose non - common sides form a straight - line. The sum of angles in a linear pair is .

Step - by - Step Solution

1. Analyze the position of angles and :

Angles and are adjacent as they have a common vertex and a common side.

Their non - common sides together form a straight - line. So, they meet the criteria for a linear pair. They are not vertical angles since they are not opposite to each other.
