angle

Angle is a measurement of the amount of turn or rotation between two lines, line segments, or rays. It is typically expressed in degrees, where one complete rotation is 360 degrees. Angles are used in math, science, engineering, and many other fields to describe the orientation or position of objects in space. They can be acute (less than 90 degrees), obtuse (greater than 90 degrees), straight (exactly 180 degrees), or right (exactly 90 degrees). Understanding angles is important for solving problems involving geometry, trigonometry, and other mathematical and scientific concepts.
