Answer:
Explanation:
Adjacent angles are two angles that share a common vertex and a common side but do not overlap. In other words, the two angles are side-by-side and their interiors do not intersect. The common side between adjacent angles is also known as their common ray or common side, and the vertex where the common side meets the two angles is known as the common vertex.
Adjacent angles are important in geometry, especially in the study of angles and geometric shapes. One example where adjacent angles are used is in the definition of a straight angle, which is an angle that measures exactly 180 degrees and can be formed by placing two adjacent angles together. Another example is in the definition of a polygon, where adjacent sides and adjacent angles are used to define the shape of the polygon.
