trapezia
[trəˈpiːziə ]
Definition
mathematics shape
A trapezium, also known as a trapezoid in American English, is a four-sided shape with at least one pair of parallel sides. Trapeziums can be classified into various types depending on the lengths of their sides and angles. The most common type, known as an isosceles trapezium, has non-parallel sides that are equal in length. The properties of trapeziums make them important in geometry, especially when calculating areas and understanding the properties of quadrilaterals.
Synonyms
Examples of usage
- The area of a trapezium can be calculated using a specific formula.
- In geometry, we often use trapeziums to demonstrate principles of surface area.
- The furniture design features a trapezium shape for aesthetic appeal.

Interesting Facts
Mathematics
- Finding the area of a trapezium involves averaging the lengths of the two parallel sides and multiplying by the height.
- Trapeziums can be classified into different types based on the lengths of the non-parallel sides: right trapeziums have one right angle, while isosceles trapeziums have non-parallel sides that are equal in length.
Architecture
- Trapezium shapes are commonly found in architectural designs like pediments and canopies, adding structural stability.
- In modern architecture, trapezium shapes are often used in facades of buildings for aesthetic and functional purposes.
Art and Design
- Trapezia shapes can be found in abstract art, where they create visual tension or balance in compositions.
- Famous artists like Piet Mondrian have utilized trapezia in their work to challenge viewers' perceptions of space and form.
Physical Fitness
- In gymnastics and circus arts, trapeze artists often use trapezium-shaped equipment to perform aerial feats, showcasing the shape's link to agility.
- The trapezius muscle in the back bears a resemblance to the trapezium shape, emphasizing how forms in biology and geometry are intertwined.
Origin of 'trapezia'
Main points about word origin
- The term 'trapezia' comes from the Greek word 'trapeza', which means 'table', referring to its flat, table-like shape.
- In geometry, 'trapezia' is the plural form of 'trapezium', which is often used in British English to describe a quadrilateral with at least one pair of parallel sides.
The term 'trapezium' comes from the Greek word 'trapezion' which means 'little table'. This term has been used in mathematical contexts since antiquity. The early geometer Archimedes described the properties of trapeziums in relation to circles and their segment areas. As mathematics evolved, the terminology became more standardized. In the 19th century, distinctions between trapezium and trapezoid were made, particularly between British and American English. Today, 'trapezium' often refers specifically to the European definition, where it denotes any quadrilateral with at least one pair of parallel sides.
