HALF A CIRCLE Meaning and
Definition
-
Half a circle refers to exactly one-half of the complete or full circumference of a circle. A circle is a two-dimensional geometric shape defined as a perfectly round, closed curve in which all points on the circumference are equidistant from the center. It can be thought of as the set of all points in a plane that are equidistant from a fixed center point. In mathematical terms, a circle can be described as the locus of all points equidistant from a given center point.
Half a circle is obtained by bisecting the circle along a diameter, which is a line segment passing through the center and having both its endpoints on the circumference. It can be visually represented as a curve that starts from one endpoint of the diameter, moves along the circumference in a semicircular path, and ends at the other endpoint of the diameter.
In terms of angular measurement, a half circle spans an angle of exactly 180 degrees or radians, corresponding to half of the total 360 degrees or 2π radians of a complete circle. It can also be seen as a straight angle, where the two rays of the angle lie along the two radii of the semicircle.
Half a circle finds applications in various fields, such as geometry, trigonometry, and engineering, as it serves as a building block for other shapes and calculations involving circular arcs.
