collocation: geometry class

In geometry, the distance around a circle is called the circumference.

uncountable noun: 'in geometry' as a field of study

同義詞
  • mathematics

    much broader field that includes geometry as one part

  • trigonometry

    a specific branch of geometry focused on triangles and angles

  • topology

    a related but more abstract field studying the properties of shapes that remain unchanged under stretching or bending

用法筆記

Almost always uncountable when referring to the academic subject. The plural form 'geometries' is rare and used only for different systems of geometry (e.g. Euclidean and non-Euclidean geometries).

常見錯誤

❌I have a geometry book.
✅I have a geometry textbook.
💡'geometry' is uncountable for the field; use 'textbook' or 'book about geometry' for the physical item.
❌Algebra is a geometry.
✅Algebra is a branch of mathematics, like geometry.
💡geometry is a distinct field, not a type of algebra.

2.名詞B2
釋義

the particular pattern or arrangement in which the parts of an object or structure are placed, especially one that affects how it looks or works.

例句

The geometry of the new sports stadium allows more sunlight to reach the field.

pattern: the geometry of + [object]

Esteban studied the delicate geometry of snowflakes using a special microscope.

同義詞
  • configuration

    more general term for the way parts are arranged; less tied to mathematical shapes

  • structure

    broader, referring to any organised whole, not just shape

  • layout

    more informal, especially for two-dimensional arrangements like floor plans

文法句型

the geometry of + [object/structure]

用法筆記

Often used with 'the ... of' pattern to describe the shape or layout of a specific object. This sense is common in design, architecture, and engineering contexts.

常見錯誤

❌The geometry of my phone case broke.
✅The geometry of my phone case makes it easy to hold.
💡geometry refers to the shape or arrangement, not the physical material.
❌I learned a new geometry today.
✅I learned about the geometry of honeycomb cells today.
💡this sense still takes an article or modifier describing which arrangement.
