Lines Geometry

What is a line?

• a straight path of points that goes on and on in two directions

• an endless flat surface

• an exact location in space

• lines that never intersect

What are parallel lines?

• Lines that form square corners

• lines that never intersect

• lines that pass through the same point

• lines that curve on an angle

What are intersecting lines?

• Lines that never cross

• lines that cross many times

• lines that cross through the same point

• Lines that are the same distance apart

What is a line segment?

• Part of a line with 2 endpoints

• Part of a line that has 1 endpoint

• Part of a line with 0 endpoints

• Part of a line with 5 endpoints
