SEMICIRCLE Meaning and
Definition
-
A semicircle is a geometric figure that consists of half of a circle. It is formed by slicing a complete circle along its diameter, resulting in a curved line that forms a half-circle. A semicircle is symmetrical, possessing two equal straight sides that extend from the endpoints of the diameter to the curved edge. The diameter of a semicircle is the line segment that passes through the center of the circle and has its endpoints on the curved edge. This diameter is considered the longest line segment within the semicircle.
The curved edge of a semicircle is called the arc, which is rounded and smooth. It spans 180 degrees, or half of the total degrees in a circle. Consequently, the central angle of a semicircle measures 180 degrees, making it a straight angle. The radius of a semicircle refers to the line segment that extends from the center of the circle to the curved edge. It is half the length of the diameter and remains constant throughout the semicircle.
The concept of a semicircle is frequently encountered in various contexts, including mathematics, geometry, construction, and architecture. It is utilized in many applications, such as calculating areas and perimeters, designing archways, and defining the boundaries of certain regions. Semicircles are also commonly found in structures, sculptures, and artwork, often adding a sense of harmony, balance, and aesthetic appeal to the overall design.
