Points, Lines, Rays, Segments, and Planes

What is the relationship between collinear points and line segments?

• Collinear points can form a line segment if they are between two endpoints.

• Collinear points can never form a line segment.

• Collinear points are always equidistant from each other.

• Collinear points can only form a triangle.

What is the definition of a straight line?

• A line that curves and has no endpoints.

• A line that does not curve and has no endpoints.

• A line that is always horizontal.

• A line that connects two points and has a definite length.

What is a line?

• A straight path that extends in opposite directions forever, such as a number line.

• A curved path that bends and does not extend infinitely.

• A collection of points that form a closed shape.

• A segment of a path that has a defined start and end point.

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

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

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

• A line is always straight, while a line segment can be curved.

• A line segment is longer than a line.

What are coplanar points?

• Points that lie on the same plane.

• Points that lie on different planes.

• Points that form a straight line.

• Points that are equidistant from a single point.

What is a ray?

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

• A line that has two endpoints and does not extend infinitely.

• A point in space that has no dimensions.

• A segment of a line that is finite in length.

What is a plane?

• A flat, two-dimensional surface that extends infinitely in all directions.

• A three-dimensional object with length, width, and height.

• A curved surface that can be bent or shaped.

• A solid object with a defined volume and mass.

What are parallel lines?

• Lines that intersect at a right angle.

• Lines in a plane that never meet and are always the same distance apart.

• Lines that converge at a point.

• Lines that are curved and do not follow a straight path.

What is a line segment?

• A part of a line that has two endpoints and includes all the points in between.

• A line that extends infinitely in both directions.

• A straight path that connects two points without any endpoints.

• A curved line that connects two points.

How do you determine if two lines are parallel?

• If two lines are in the same plane and do not intersect, they are parallel.

• If two lines have the same slope, they are parallel.

• If two lines are perpendicular to each other, they are parallel.

• If two lines intersect at a right angle, they are parallel.
