kvadránszögre
Kvadránszögre is a term originating from Hungarian mathematics, referring to a specific type of angle measurement. It literally translates to "quadrant angle" and is used in contexts where angles are considered within the Cartesian coordinate system. Specifically, a kvadránszögre describes an angle that falls entirely within one of the four quadrants. These quadrants are defined by the intersection of the x-axis and the y-axis, dividing the plane into four regions. A kvadránszögre is an angle whose terminal side, when drawn in standard position (vertex at the origin, initial side along the positive x-axis), lies strictly within one of these four regions. This excludes angles that lie on the axes themselves (0, 90, 180, 270 degrees, and their multiples), as these are considered boundary angles and not strictly within a quadrant. The measurement of a kvadránszögre can be expressed in degrees or radians. Understanding kvadránszögre is fundamental in trigonometry and analytical geometry for accurately locating points and analyzing geometric figures on the coordinate plane.
