Points, Lines, Line Segments, Rays

Point

A single spot or an exact location

Line

A line goes on forever in both directions.

You may see points named on the line, but if the arrows are there, it is a line.

Line Segment

It is a portion of a line that has a point at both ends.

Ray

A part of a line that has a point at one end and the opposite ends continues infinitely. This wll be indicated with an arrow.

Angel

An angel is where 2 lines intersect.

Multiple Choice

What is a point?

• a straight path
• an exact location
• endless flat surface
• lines that cross

Multiple Choice

What does the image show? 
(The whole thing, not just the points)

• a ray
• a line
• a line segment
• a point

Multiple Choice

What does the image show?

(The whole thing, not just the points)

• a ray

• a line

• parallel lines

• line segment

Line Segment ab

Ray a

When we state the ray's name, we start with the point - ray ab.

You start with the name of the point without an arrow.

Line tx

Parallel Lines

• Two or more lines continue in the same direction and maintain the same distance apart the entire length.

• They NEVER cross.

• Lines tx and yw are parallel lines.

• Think of railroad tracks

Intersecting Lines

• Two or more lines that cross each other.

• Lines pn and rs are intersecting lines.

Perpendicular Lines

• Two lines intersect creating a right angle -  $90^o$ . 

• A right angle makes a square.

• Lines xw and yt are perpendicular lines.

• Think about 2 roads intersecting.
