Lines, Line segments, and Rays

Front

What is a line?

Back

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

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What is a ray?

Back

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

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

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.

Front

Can a ray be part of a line segment?

Back

No, a ray starts at one point and extends infinitely, while a line segment has two endpoints.

Front

What is an example of parallel lines in real life?

Back

Train tracks are an example of parallel lines.

Front

What is an example of intersecting lines in real life?

Back

The intersection of roads is an example of intersecting lines.
