Excerpt:, the angle symbolIn geometry, an angle (in full, plane angle ) is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other (see "Measuring angles," below). Where there is no possibility of confusion, the term "angle" is used interchangeably for both the geometric configuration itself and for its angular magnitude (which is simply a numerical quantity).The word angle comes from the Latin word angulus, meaning "a corner." The word angulus is a diminutive, of which the primitive form, angus, does not occur in Latin. Cognate words are the Greek (ankyl s), meaning "crooked, curved," and the English word "ankle ." B...
