Definition
Two sides of a polygon that share a common endpoint (vertex).
In simple terms:
Sides that are next to each other and meet at a corner.
Example:
In parallelogram ABCD, sides AB and BC are adjacent because they meet at point B.
Important Note (Parallelograms):
Adjacent sides are consecutive sides and are not parallel to each other (unlike opposite sides).
