Points, Lines, and Planes

What are opposite rays?

• Two rays that share the same endpoint and extend in opposite directions.

• Two rays that share the same length and direction.

• Two rays that do not share any points.

• Two rays that are parallel to each other.

How do you denote a line?

• A line is typically denoted by two points on the line, such as line @@AB@@.

• A line is represented by a single point on the line.

• A line is denoted by a number indicating its length.

• A line is shown as a dashed line on a graph.

What does it mean for two lines to be parallel?

• Two lines are parallel if they are in the same plane and do not intersect, no matter how far they are extended.

• Two lines are parallel if they intersect at a right angle.

• Two lines are parallel if they are in different planes and do not meet.

• Two lines are parallel if they are equidistant from each other at all points.

How do you represent a line segment?

• A line segment is represented by its endpoints, such as @@\overline{AB}@@.

• A line segment is represented by its midpoint only.

• A line segment is represented by its length only.

• A line segment is represented by a single point.

What is the significance of the intersection point E in geometry?

• The intersection point E represents the location where line HE meets plane DGF.

• The intersection point E is the midpoint of line segment HG.

• The intersection point E indicates the center of a circle.

• The intersection point E is where two parallel lines cross.

What is a Line Segment?

• A line segment is a part of a line that is bounded by two distinct endpoints. It has a definite length.

• A line segment is an infinite length of a line without any endpoints.

• A line segment is a curved line that connects two points.

• A line segment is a straight line that extends infinitely in both directions.

What is a point in geometry?

• A point is a specific location in space that has no size or dimension.

• A point is a geometric figure with length and width.

• A point is a line segment that connects two endpoints.

• A point is a shape that occupies space.

What is a Right Angle?

• An angle that measures exactly 90 degrees.

• An angle that measures exactly 45 degrees.

• An angle that measures less than 90 degrees.

• An angle that measures more than 180 degrees.

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

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

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

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

• A line segment is longer than a line.

What is the notation for a ray?

• @@ ightarrow{AB}@@

• @@ ightarrow{A}@@

• @@ ightarrow{ABCD}@@

• @@ ightarrow{A-B}@@
