#### Answer

The even vertices are vertex A and vertex B.
The odd vertices are vertex C, vertex D, vertex E, and vertex F.

#### Work Step by Step

An even vertex is a vertex with a degree that is an even number. An odd vertex is a vertex with a degree that is an odd number.
The degree of vertex A is 2, so vertex A is an even vertex.
The degree of vertex B is 2, so vertex B is an even vertex.
The degree of vertex C is 3, so vertex C is an odd vertex.
The degree of vertex D is 3, so vertex D is an odd vertex.
The degree of vertex E is 3, so vertex E is an odd vertex.
The degree of vertex F is 1, so vertex F is an odd vertex.
