Understanding Rays, Lines, and Segments

Which of the following best describes a line?

• A path that extends infinitely in one direction.

• A path that extends infinitely in two directions.

• A path that has a fixed start and end point.

• A path that curves infinitely.

What is a line segment?

• A part of a line that extends infinitely in one direction.

• A part of a line that extends infinitely in two directions.

• A part of a line that has two endpoints.

• A curved path between two points.

Which of the following best describes a ray?

• A straight path that has a fixed length.

• A straight path that extends infinitely in one direction from a given point.

• A straight path that extends infinitely in two directions.

• A curved path that extends infinitely in one direction.

Identify the figure that represents a line segment.

• A straight path with arrows on both ends.

• A straight path with one arrow on one end.

• A straight path with no arrows and two endpoints marked.

• A curved path with two endpoints marked.

Which of the following is an example of parallel lines?

• Two lines that intersect at a 90-degree angle.

• Two lines that never intersect and are the same distance apart.

• Two lines that intersect at some point.

• Two lines that curve away from each other.

What characterizes perpendicular lines?

• Lines that run parallel to each other.

• Lines that intersect to form a 45-degree angle.

• Lines that intersect to form a 90-degree angle.

• Lines that never intersect.

Draw a line segment and label its endpoints as A and B.

• A straight path with arrows on both ends labeled A and B.

• A curved path with endpoints labeled A and B.

• A straight path with no arrows and endpoints labeled A and B.

• A straight path with one arrow, starting at A and pointing towards B.

How can you identify a ray from a diagram?

• It will have two arrows on both ends.

• It will have one arrow on one end and a marked starting point.

• It will have no arrows and two marked endpoints.

• It will be a curved line with an arrow on one end.

Which of the following statements is true about lines?

• They have a definite starting and ending point.

• They can only extend infinitely in one direction.

• They extend infinitely in two directions and have no endpoints.

• They are always curved.

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

• A ray has two endpoints, while a line segment has only one.

• A ray extends infinitely in two directions, while a line segment does not.

• A ray extends infinitely in one direction, while a line segment has two definite endpoints.

• There is no difference; they are the same.
