PLEASE HELPPPP Using the diagram below, which of the following angle pairs represent vertical angles?

DCE and BCA

Step-by-step explanation:

Vertical angles are angles which lie directly opposite each other on intersecting lines. Because of this they are equal, and share the same vertex. Out of these pairs, only DCE and BCA are vertical angles because they lie opposite to each other on the lines FJ and IM, and share a vertex of point C.

Hope this helped!
