Naming Segments, Lines, Rays and Angles

How do you denote a ray?

• A ray is denoted by its endpoint and another point, e.g., \overrightarrow{AB}.

• A ray is denoted by two endpoints, e.g., \overline{AB}.

• A ray is denoted by a single point, e.g., A.

• A ray is denoted by a line segment, e.g., AB.

What is a transversal?

• A line that intersects two or more lines at different points.

• A line that runs parallel to another line.

• A line that is perpendicular to another line.

• A line that connects two points on a curve.

What are vertical angles?

• Angles that are adjacent to each other when two lines intersect.

• Angles that are opposite each other when two lines intersect; they are always equal.

• Angles that are supplementary to each other when two lines intersect.

• Angles that are complementary to each other when two lines intersect.

How do you denote a line segment?

• A line segment is denoted by the endpoints with a line over them, e.g., @@\overline{AB}@@.

• A line segment is denoted by the endpoints without any notation.

• A line segment is denoted by a dashed line between the endpoints.

• A line segment is denoted by the letters A and B only.

What is an angle?

• An angle is formed by two rays that share a common endpoint, called the vertex.

• An angle is a straight line that measures 180 degrees.

• An angle is a figure formed by three points in a plane.

• An angle is the space between two intersecting lines.

What is a line?

• A line is a straight path that extends infinitely in both directions with no endpoints.

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

• A line is a segment that has a fixed length.

• A line is a collection of points that form a closed shape.

What is a complementary angle?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

What is a supplementary angle?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

What is the vertex of an angle?

• The point where the two rays meet.

• The angle formed by two intersecting lines.

• The length of the angle's sides.

• The area enclosed by the angle.

How do you denote a line?

• A line is denoted by two points on the line with a double-headed arrow over them, e.g., \( \overleftrightarrow{AB} \).

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

• A line is indicated by a dashed line connecting two points.

• A line is shown as a straight line without any markings.
