What are Adjacent Angles?

In geometry, adjacent angles are two angles that share a common vertex and a common side but do not overlap. Think of them as angles that are side-by-side.

Common Vertex: Both angles must originate from the same point.
Common Side: They must share one ray that forms a side for both angles.
Non-overlapping: Adjacent angles do not have any interior points in common.

For example, imagine two slices of pizza next to each other. The angles formed by these slices at the center of the pizza are adjacent if they share a common edge (side) and meet at the same point (vertex), without overlapping.
