Adjacent angles : Two angles in a plane are called adjacent-angles, if 1) they have a common vertex, 2) they have a common arms (rays), and Every angle can have two different angles adjacent to it, one on each side of it. E-learning is the future today. If a ray stands on a line, then the sum of adjacent angles formed is 180∘ 180 ∘ If the sum of two adjacent angles is 180∘ 180 ∘, then they are called a linear pair of angles. Adjacent Angles: In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Plane-related angles The angle between two planes (such as two adjacent faces of a polyhedron) is called a dihedral angle.
