In mathematics and geometry, adjacent sides refer to sides that share a common endpoint or vertex. Adjacent sides can be found in various two-dimensional shapes, such as squares, rectangles, triangles, and polygons.

For example, in a square, each of the four sides is adjacent to the two sides it touches. In a rectangle, two sides that are opposite each other are referred to as "opposite sides," while the other two sides are considered to be adjacent. Any two sides that share a common vertex are considered to be adjacent sides in a triangle.

Adjacent sides play an important role in many geometric calculations and measurements, such as finding the perimeter of a shape, calculating the area, and determining the interior and exterior angles of a shape. By understanding the relationships between adjacent sides, it is possible to make more precise calculations and predictions about various shapes and figures.
