Answer:
∠1, ∠A, ∠PAL, ∠LAP
Step-by-step explanation:
Looking the the diagram, we can see that an angle there is ∠1. This means it was labeled using numbers.
Now, we can also label it using vertex and so another way of writing it is ∠A
Now we can also label using a vertex and a point on each arm.
Thus, we can have;
∠PAL or ∠LAP
The four way labels are;
∠1, ∠A, ∠PAL, ∠LAP
