### Adjacent parts of a polygon

 Figure 1 - Polygon

In the polygon in figure 1:

• the angles A and B are adjacent,
• the sides g and h are adjacent, and
• angle A is adjacent to side g.

However,

• angle A is not adjacent to angle C,
• side g is not adjacent to angle D, and
• sides g and i are not adjacent.
