tiếp liên
Definition
- Noun:
- Contingence: In geometry, the point of contact or the state of touching between a curve and its tangent line or between two surfaces. This is a specialized mathematical term.
Usage Examples

- Góc tiếp liên là một khái niệm trong hình học vi phân. (The angle of contingence is a concept in differential geometry.)
- Nhà toán học nghiên cứu tính chất tại điểm tiếp liên. (The mathematician studies the properties at the point of contingence.)
Advanced Usage
- This term is highly technical and is almost exclusively used in advanced mathematical contexts, particularly in differential geometry, to describe the precise nature of contact between geometric objects.

Notes on Usage
- "Tiếp liên" is an extremely rare and archaic term in modern Vietnamese. It is a direct loan translation from French ("angle de contingence") and is not used in everyday language or standard education. The more common and understood term for related concepts is "tiếp xúc" (contact) or terms like "tiếp tuyến" (tangent). Learners are very unlikely to encounter this word outside of historical or highly specialized mathematical texts.
