Understanding Rays, Lines, and Angles

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

• A line is shorter than a line segment.

• A line has only one endpoint.

• A line segment has a clear start and end.

• A line segment goes on forever in both directions.

How do you correctly name a ray?

• Use any two points on the ray.

• Start with the endpoint and use another point on the ray.

• Start with the point where the ray ends.

• Start with any point on the ray.

What are lines called when they cross each other?

• Diverging lines

• Intersecting lines

• Parallel lines

• Perpendicular lines

What do you call lines that never meet, no matter how far they extend?

• Intersecting lines

• Parallel lines

• Perpendicular lines

• Converging lines

In the challenging problem, what is the relationship between ray AB and the line segments XY and SR?

• Ray AB is parallel to XY and SR.

• Ray AB is perpendicular to XY and SR.

• Ray AB intersects XY and SR at an angle other than 90 degrees.

• Ray AB does not intersect with XY and SR.
