In the illustration, angles A and B are adjacent.

In geometry, adjacent angles, often shortened as adj. ∠s, are angles that "enclosed" have a common ray coming out of the vertex going ,with no overlap of the regions by the two angles. In other words, they are angles that are side by side, or adjacent between two other rays,

Complementary adjacent angles

A pair of angles is complementary if the sum of their measures is 90°.

A pair of angles is supplementary if the sum of their measures is 180°. Example angle A is 40° and angle B is 140° this is a supplementary angle An angle with a ray connected to a common point down the center. In geometry, two angles are adjacent angles if they share a common vertex and side, but have no common interior points.
