tương đẳng
Definition
- Adjective:
- Congruent / Equipollent: In mathematics, "tương đẳng" describes geometric figures that are identical in shape and size. It is a direct equivalent to the geometric concept of congruence.
- Equivalent / Corresponding: More broadly, it can describe things that are equal in value, force, or meaning, and thus can be considered counterparts.
Usage Examples
- Adjective:
- Hai tam giác này là tương đẳng. (These two triangles are congruent.)
- Hai lực lượng tương đẳng sẽ tạo ra thế cân bằng. (Two equivalent forces will create a balance.)
- Trong bản dịch, tìm một từ tương đẳng về sắc thái rất khó. (In translation, finding a word with an equivalent nuance is very difficult.)
Advanced Usage
- "tương đẳng hình học": geometric congruence.
- Định lý này chứng minh sự tương đẳng hình học của hai đa giác. (This theorem proves the geometric congruence of the two polygons.)
Variants and Related Words
- Tương đương (adj): equivalent, often used more broadly in non-mathematical contexts for equivalence in function or value.
- Hai công thức này có tác dụng tương đương. (These two formulas have an equivalent effect.)
Synonyms
- Congruent: Coinciding exactly when superimposed (mathematics).
- Equivalent: Equal in value, measure, force, effect, or significance.
- Identical: Exactly alike.
Related Terms
- Đẳng cấu (adj): isomorphic, a related but distinct concept in advanced mathematics indicating a structure-preserving mapping.
- Đồng dạng (adj): similar (in geometry), meaning same shape but not necessarily the same size.
