Question Analysis

This question focuses on the concept of linear pairs of angles.

Key Concept Explanation

A linear pair consists of adjacent angles that share a common vertex and a common side, with their non - common sides forming a straight line. The sum of the angles in a linear pair is 180°.

Step - by - Step Solution

1. Analyze each option:

A.Angles b and g:

These angles are not adjacent. They don't share a common vertex and a common side as required for a linear pair. So, they do not form a linear pair.

B.Angles j and k:

Angles j and k are adjacent, sharing a common vertex and a common side. Their non - common sides form a straight line. Thus, they form a linear pair.

C.Angles a and i:

They are not adjacent and have no relevant relationship to form a linear pair. They are located on different intersections and don't share the necessary common elements.

D.Angles f and h:

These are vertical angle...
