In Geometry, there are five fundamental angle pair relationships: Complementary Angles, Supplementary Angles, Adjacent Angles, Linear pairs, and Vertical Angles. Basically, geometry angle relationships mean correlation of an angle with its surrounding angles on the same plane. An angle in Geometry is created from two or more lines intersecting each other.

Several types of angle relationships are there in geometry.

Complementary angles are two corresponding angles whose sum is 90 degrees.

Supplementary angles are two corresponding angles whose sum is 180 degrees.

Adjacent angles are two angles in a plane that have a common vertex and a common side but no common interior points.

A linear pair is precisely what its name indicates. It is a pair of angles sitting on a line. A linear pair forms supplementary angles.

Vertical angles are two nonadjacent angles formed by two intersecting lines or opposite rays.
