Question Analysis
This question involves the understanding of vertical angles and linear pairs of angles formed by intersecting lines.
Key Concept Explanation
Vertical angles: Occur when two lines intersect. They are opposite each other and have equal measures.
Linear pair: A pair of adjacent angles that together form a straight - line, so their sum is .
Step - by - Step Solution
1. Analyze the position of angles and :
Angles and are adjacent as they share a common vertex and a common side.
However, they do not form a straight - line. Also, they are not opposite each other. So, they are neither vertical angles nor a linear pair.
Option Analysis
A.vertical angles: Incorrect because
