gónía
Gónía, also known as gonia or gonion, is a term derived from the Greek word "gōnía," meaning "angle." In mathematics, gónía refers to the measure of an angle, typically expressed in degrees or radians. Angles are fundamental in geometry and trigonometry, representing the amount of rotation between two rays that share a common endpoint, known as the vertex. Angles can be classified as acute (less than 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), right (exactly 90 degrees), straight (exactly 180 degrees), reflex (greater than 180 degrees but less than 360 degrees), and full (exactly 360 degrees). The study of angles is crucial in various fields, including physics, engineering, and computer graphics, where they are used to describe the orientation and movement of objects. In everyday language, the term "gónía" can also refer to a corner or a point where two lines or surfaces meet, emphasizing the geometric concept of an angle.
