Answer:
1. linear pair (c and d)
2. alternate interior angles (c and f)
Step-by-step explanation:
Here, we want to get the relationship between angles
From what we have , we can see that angle d and angle c lie on a straight line
Thus, we have that angle c and angle d are supplementary angles since they will add up to give 180 degrees . So we can call the two a linear pair
For c and f, we can notice a z-like angle between the two
In this case, when we have a z-like angle, the relationship that exists between the two angles is that they are alternate interior angles
