They are called adjacent angles.

Explanation:

Adjacent means "next to". Any time we have an angle (like #angle ABC# below), we can create an adjacent angle to it, by picking a point #D# "outside" the angle, and connecting #BD#.

We now have the two adjacent angles #angle ABC# and #angle CBD.#

The common vertex is #B#, and the common side is #BC.#
