∠DOC, ∠COB and ∠BOA

1) To name all the angles, we need to write this way:

1.2) The name of the angle starts with the point, the vertex, and the endpoint. This way:

In this picture, we have the following angles (left to the right)

∠DOC Always in capital letters

∠COB

∠BOA

Note that the vertex is always at the middle, between the endpoints.

∠COB is the same angle as ∠BOC the order of the endpoints make no difference.

2) Hence, the answer is:∠DOC, ∠COB and ∠BOA
