Angle
A figure formed by two rays with a common endpoint.
An angle is a geometric figure that consists of two rays that share a common endpoint. The common endpoint is called the vertex of the angle, and the two rays are called the sides of the angle. Angles are usually measured in degrees or radians and can be used to determine the relative positions of objects in geometrically constructed figures.
Angles can be classified based on their size in relation to a straight angle, which is an angle that measures 180 degrees. An acute angle measures less than 90 degrees, a right angle measures exactly 90 degrees, an obtuse angle measures greater than 90 degrees but less than 180 degrees, and a straight angle measures exactly 180 degrees.
Angles are used in many fields, including mathematics, physics, engineering, and architecture. They are essential in developing accurate models of objects and structures, as well as in solving problems involving distance, movement, and trigonometry.
