What is a line in geometry?

Back

A line is a straight path that extends infinitely in both directions and has no endpoints.

Front

What is a line segment?

What is the geometric notation for a ray starting at point K and passing through point J?

Back

The geometric notation is @@ ightarrow{KJ}@@.

Front

What is the difference between parallel lines and intersecting lines?

Back

Parallel lines never meet, while intersecting lines cross each other.

Front

Can a line segment be longer than a ray?

Back

Yes, a line segment has a fixed length, while a ray extends infinitely.
