Lines, Line Segments, Rays, Perpendicular, and Parallel Lines

What is the study of geometry primarily concerned with?

• The characteristics and relationships of numbers

• The characteristics, measurements, and relationships of points, lines, angles, surfaces, and solids

• The study of calculus and its applications

• The study of algebraic equations

How do we label a line that passes through points A and B?

• Line A to B

• Line AB

• Line B to A

• Line BA

What is a key characteristic of a ray?

• It is always parallel to another line

• It extends infinitely in one direction

• It has both a starting and an ending point

• It forms a 90-degree angle with another line

Which of the following best describes parallel lines?

• Lines that intersect at any angle

• Lines that are part of a triangle

• Lines that never intersect and remain equidistant

• Lines that intersect at a 90-degree angle

What is the relationship between line segments AB and CD if they intersect at a 90-degree angle?

• They are skew

• They are parallel

• They are perpendicular

• They are collinear

How can you identify perpendicular lines?

• They never meet

• They form a 90-degree angle at the intersection

• They are always parallel

• They are part of a circle

What is a plane in geometry?

• A point with no dimensions

• A three-dimensional object

• A flat surface with no edges

• A line that extends infinitely
