hemicircle
[หhษmษชหsษrkl ]
Definition
geometry
A hemicircle is a half of a circle or a shape that is formed by dividing a circle along its diameter. It consists of the arc of the circle and the line segment that represents the diameter. Hemicircles are used in various applications in mathematics, architecture, and design.
Synonyms
half-circle, semicircle.
Examples of usage
- The playground features a hemicircle seating area.
- We studied the properties of a hemicircle in our geometry class.
- The design of the amphitheater included a large hemicircle.
- To calculate the area, we divided the circle into two hemicircles.

- The forces acting on a hemicircular shape in fluid dynamics can help scientists understand flow patterns.
Pop Culture
- Hemicircles are often featured in movie scenes where characters interact in a semi-circular seating arrangement, promoting discussion.
- In sports, some arenas and stadiums are designed in a hemicircular or semi-circular layout to enhance audience experience.
Origin of 'hemicircle'
Main points about word origin
- The term comes from the Greek words 'hฤmi' meaning 'half' and 'kyklos' meaning 'circle'.
- It has been used in geometry for centuries to describe half of spherical objects.
The term 'hemicircle' comes from the combination of the Greek prefix 'hemi-', meaning 'half', and the Latin 'circus', meaning 'circle'. This linguistic formation indicates that a hemicircle is essentially a divided circle. The concept of a hemicircle has been prevalent in mathematics since ancient times when Greeks studied the properties of circles and their sections, employing various geometric principles. The hemicircle plays a significant role in architecture and engineering, where half-circular designs are often used for aesthetic and functional purposes. The study of hemicircles also extends to the field of physics, especially in concepts involving wave patterns and circular motion.
