Naming Lines, Line Segments, and Rays | Geometry | Math with Mr. J

What is a key characteristic of a line in geometry?

• It has one endpoint and extends infinitely in one direction.

• It has two endpoints and a definite length.

• It extends infinitely in both directions.

• It is a curved path between two points.

If a line passes through points P and Q, how can it be named using standard geometric notation?

• PQ (with a line segment symbol above)

• PQ (with a line symbol with arrows above)

• PQ (with a ray symbol above)

• Point P and Point Q

Which statement accurately describes a line segment?

• It extends infinitely in one direction from a starting point.

• It has a curved path with no defined end.

• It has two distinct endpoints and a measurable length.

• It is a straight path that goes on forever.

How would you correctly name a line segment with endpoints A and B using standard geometric notation?

• AB (with a line symbol with arrows above)

• AB (with a ray symbol above)

• AB (with a line segment symbol above)

• Line AB (written out as "Line AB")

How is a line segment with endpoints M and N correctly represented?

• MN with a ray symbol over it

• MN with a line symbol over it

• MN with a bar over it

• MN without any symbol

For a line segment, which statement about naming is true?

• The order of the two endpoints always matters.

• The order of the two endpoints does not matter.

• Only one specific name is allowed for each segment.

• Line segments cannot be named using letters.

What is the correct way to name a ray?

• Start with any point on the ray, then the endpoint.

• Start with the endpoint, then any other point on the ray.

• List all points on the ray in alphabetical order.

• Rays cannot be named using letters.

If a ray has endpoint A and passes through point B, how should it be written?

• Ray BA (with ray symbol pointing right)

• Segment AB (with segment bar)

• Ray AB (with ray symbol pointing right)

• Line AB (with line symbol)
