Points, lines, rays, and angles

What are right angles?

• Angles that measure exactly 90 degrees.

• Angles that measure exactly 45 degrees.

• Angles that measure exactly 180 degrees.

• Angles that measure exactly 60 degrees.

What is a ray?

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

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

• A ray is a point in space that has no length or width.

• A ray is a curved line that bends in one direction.

What is a line segment?

• A line that extends infinitely in both directions.

• A part of a line that has two endpoints.

• A line that curves and does not have endpoints.

• A line that is only vertical.

What is a line?

• A line is a curved path that has two endpoints.

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

• A line is a segment that connects two points.

• A line is a shape that has width and height.

Can a line segment be longer than a ray?

• Yes, a line segment has fixed endpoints, while a ray extends infinitely in one direction.

• No, a ray is always longer than a line segment.

• Yes, both a line segment and a ray can be of equal length.

• No, a line segment cannot be longer than any other geometric figure.

What is the vertex of an angle?

• The point where two rays meet.

• The angle formed by two intersecting lines.

• The length of the angle's sides.

• The area enclosed by the angle.

What does it mean for lines to be perpendicular?

• They are lines that never intersect.

• They are lines that intersect at a right angle (90 degrees).

• They are lines that are parallel to each other.

• They are lines that intersect at an acute angle.

What is a transversal line?

• A line that runs parallel to another line.

• A line that crosses two or more other lines, creating angles.

• A line that is perpendicular to another line.

• A line that connects two points on a graph.

What are obtuse angles?

• Angles that measure less than 90 degrees

• Angles that measure exactly 90 degrees

• Angles that measure more than 90 degrees but less than 180 degrees

• Angles that measure more than 180 degrees

What is an angle?

• An angle is formed by two rays that share a common endpoint.

• An angle is a measure of the distance between two points.

• An angle is a type of polygon with three sides.

• An angle is the space between two parallel lines.
