Answer/Step-by-step explanation:
Relationship of angle pairs considering the given diagram are as follows:
1. <d and <e are alternate interior angles. They are opposite inner sides of the transversal.
2. <e and <h are vertically opposite angles. They share the same vertex (corner) formed by the two line that crossed.
3. <a and <e are corresponding angles. They occupy the same position as a line crosses the other two lines together.
4. <c and <d are a linear pair. They are angles on a straight line and are supplementary.
