góc so le
Definition
- Noun (Geometry):
- Alternate angles: A pair of angles that are equal in measure, formed when a straight line (a transversal) intersects two parallel lines. These angles are located on opposite sides of the transversal and on the interior of the two parallel lines.
Usage Examples
- Noun:
- Trong hình này, cặp góc so le được đánh dấu màu đỏ. (In this diagram, the pair of alternate angles is marked in red.)
- Nếu hai đường thẳng song song thì các góc so le bằng nhau. (If two lines are parallel, then the alternate angles are equal.)
- Để chứng minh hai đường thẳng song song, ta có thể chỉ ra một cặp góc so le bằng nhau. (To prove two lines are parallel, we can show that a pair of alternate angles is equal.)
Advanced Usage
- "góc so le trong": This is the full and precise term, meaning "interior alternate angles." It specifies that the angles are on the interior of the two parallel lines.
- Định lý về góc so le trong là một công cụ quan trọng trong hình học. (The theorem of interior alternate angles is an important tool in geometry.)
