Objectives Understand different types of “lines”Understand different types of “lines” Learn the correct notation for these about two pointsLearn the correct notation for these about two points Use correct notation for situations when things are parallel and perpendicularUse correct notation for situations when things are parallel and perpendicular

Lines In mathematics, what is a line? A line is in length in both directions and is. infinite straight Notation for this is:

Line Segments What is a line segment? A line segment is also straight and in length. finite Notation for this is: Note: Writing things in alphabetical order is preferred.

Rays What is a ray? A ray is in length and is bound by one point but passes through another. infinite Notation for this is:

Answers Ray Line Line Segment

Relationships These lines are parallel. These lines segments are perpendicular. These rays intersect.

Answers Its name must refer to the end points of the line segment Something with position that has no size
