In 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. Measuring angles is a fundamental skill in geometry, and there are several methods to determine the measure of an angle accurately.
Measuring angles is crucial for various applications, including architecture, engineering, navigation, and astronomy. In architecture, angles are used to design buildings, bridges, and other structures. In engineering, angles are essential for designing machines, vehicles, and other mechanical systems. In navigation, angles are used to determine the direction and position of objects. In astronomy, angles are used to measure the positions of stars, planets, and other celestial bodies.
