What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

How can a line be named?

Back

A line can be named using any two points on the line or a lowercase letter.

Front

What is the notation for a line segment?

Back

A line segment is denoted by the endpoints with a line over them, e.g., AB.

Front

What is the notation for a ray?

Back

A ray is denoted by its starting point and another point, e.g., AB, with an arrow over it starting from A.

Front

How many points are needed to define a line?

Back

Two points are needed to define a line.

Front

What is the intersection of two lines?

Back

The intersection of two lines is the point where they meet.
