[ kษnหkeษชv ]
shape description
Concave refers to a shape or surface that curves inward, resembling a bowl. This term is often used in geometry to describe figures, such as concave polygons, where at least one interior angle is greater than 180 degrees. In optics, concave mirrors are designed to direct light to a focal point, and are commonly used in telescopes and reflectors. The concept is widely found in various fields, including art and architecture, where concave structures can create unique visual effects.
Synonyms
curved inward, depressed, hollow
Examples of usage
- The mirror is concave, providing a magnified view.
- In geometry, a concave polygon has points that curve inward.
- The artist used a concave lens to create a special effect.

Word origin
The word 'concave' is derived from the Latin term 'concavus', which means 'hollow' or 'arched'. It is formed from 'con-' meaning 'with' and 'cavus' meaning 'hollow'. The usage of the word can be traced back to the late 15th century when it began to appear in mathematical and scientific contexts, particularly in describing shapes in geometry. The term gained prominence in various fields, including optics, where concave mirrors were essential for focusing light. Over time, 'concave' has been adopted more broadly in art and architecture to describe inwardly curving surfaces or forms. Today, it is a common descriptor in both everyday and technical language.
