Understanding Points, Lines, Line Segments, and Rays

What is a point?

• A straight path that continues forever in both directions

• A part of a line with one endpoint

• An exact position or location

• A part of a line with two endpoints

How do you draw a point?

• Draw two rays that share a common endpoint

• Draw a straight path with one arrow

• Draw a dot and label it with a letter

• Draw a straight path with arrows on both ends

What does a line do?

• It forms an angle

• It has one endpoint and continues forever in one direction

• It has two endpoints

• It continues forever in both directions

How do you name a line?

• Using the endpoint and another point on the line

• Using only one point on the line

• Using the vertex and two other points

• Using any two points on the line

What is a line segment?

• Two rays that share a common endpoint

• A part of a line with two endpoints

• A part of a line with one endpoint

• A straight path that continues forever in both directions

How do you name a line segment?

• Using any two points on the line

• Using the endpoint and another point on the line

• Using its endpoints

• Using the vertex and two other points

What is a ray?

• A part of a line with two endpoints

• A straight path that continues forever in both directions

• A part of a line with one endpoint and continues forever in one direction

• Two rays that share a common endpoint

How do you name a ray?

• Using only one point on the ray

• Using the vertex and two other points

• Using the endpoint and another point on the ray

• Using any two points on the line

What forms an angle?

• A part of a line with one endpoint

• A part of a line with two endpoints

• A straight path that continues forever in both directions

• Two rays or line segments that share a common endpoint

How do you name an angle?

• Using any two points on the line

• Using only one point on the line

• Using the endpoint and another point on the line

• Using the vertex and two other points
