### Adjacent Side to Vertex

Each vertex of a polygon is formed by the intersection of two sides.

The two sides that form a particular vertex are referred to as the **adjacents** of that vertex, or described as **adjacent to** that vertex.

### Adjacent Sides

Two sides of a polygon that meet at the same vertex are **adjacent** to each other.

### Adjacent Vertex to Side

Each side of a polygon intersects two other sides, and so is terminated at either endpoint by two vertices.

The two vertices that terminate a particular side are referred to as the **adjacents** of that side, or described as **adjacent to** that side.

### Adjacent Vertices

Those two vertices are described as **adjacent to each other**.
