Exploring Points, Line Segments, Lines, and Rays

What is a point in geometry?

• A dot labeled with a name

• A line with two endpoints

• A ray with one endpoint

• A line that extends infinitely

How do you label a point?

• With a number

• With a color

• With a letter

• With a symbol

What is a line segment?

• A line that extends infinitely

• A line with one endpoint

• A line with two endpoints

• A dot labeled with a name

How can you name a line segment?

• Two ways

• Four ways

• Only one way

• Three ways

What is the main difference between a line and a line segment?

• A line segment has no endpoints

• A line has two endpoints

• A line extends infinitely, while a line segment has two endpoints

• A line segment extends infinitely, while a line has two endpoints

How do you name a line?

• With a single letter

• With two letters and a line with arrows over them

• With a symbol

• With a number

What is a ray in geometry?

• A line with two endpoints

• A line that extends infinitely in both directions

• A line with one endpoint and extends infinitely in one direction

• A dot labeled with a name

How do you name a ray?

• With a single letter

• Starting with the endpoint and then the other point

• With a number

• Starting with the point near the arrow

What does an arrow on a line or ray indicate?

• It has a beginning and an end

• It is a point

• It extends infinitely in that direction

• It is a line segment

Which of the following statements is true about a line segment?

• It has a beginning and an end

• It has no endpoints

• It extends infinitely in one direction

• It extends infinitely in both directions
