Lines

What is an example of parallel lines in real life?

• Train tracks

• The path of a river

• The edge of a mountain

• The curve of a road

Can two lines be both parallel and intersecting?

• Yes, they can be both parallel and intersecting.

• Only if they are in different planes.

• No, two lines cannot be both parallel and intersecting; they are mutually exclusive.

• It depends on the dimensions of the space.

How can you identify a ray in a diagram?

• A ray is identified by a starting point and an arrow indicating it extends infinitely in one direction.

• A ray is represented by two endpoints and does not extend infinitely.

• A ray is a straight line that has no starting point.

• A ray is identified by a curved line that extends in both directions.

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 is a straight path that can be measured, while a line segment cannot be measured.

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

• A line is always horizontal, while a line segment can be vertical or horizontal.

What is a parallel line?

• Lines that intersect at a right angle.

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

• Lines that curve away from each other.

• Lines that meet at a point.

What is an intersecting line?

• A line that runs parallel to another line.

• A line that crosses another line at one point.

• A line that never meets another line.

• A line that forms a right angle with another line.

What is the symbol for a line segment?

• AB

• AB with a dot above

• AB with a squiggly line

• AB with a double line

What is the term for the angle formed by two intersecting lines?

• Intersection angle

• Acute angle

• Obtuse angle

• Right angle

What is the relationship between intersecting lines and angles?

• Intersecting lines create angles at the point where they cross.

• Intersecting lines do not create any angles.

• Intersecting lines only create acute angles.

• Intersecting lines create parallel angles.

How many points are needed to define a line?

• One point

• Two points

• Three points

• Four points
