Geometry Worksheets: Lines, Rays, and Line Segments
Use the worked example and teaching sequence below to explain the reasoning before independent practice.
Use New Numbers to make another set. Choose Worksheet or Answer Key, then use the worksheet’s Print button.
Teaching Notes
Use the worked example and teaching sequence below to explain the reasoning before independent practice.
Before You Begin
- Recognize endpoints and arrowheads.
Teaching Steps for Parents and Teachers
- A line extends in both directions.
- A ray has one endpoint and extends in one direction.
- A line segment has two endpoints; use arrowheads only for extending directions.
Worked Examples
Which has two endpoints: a line, a ray, or a line segment?
- A line has no endpoints.
- A ray has one endpoint.
- A line segment has two endpoints.
Answer: Line segment
Common Mistakes and How to Help
Do not use arrowheads in place of endpoints.
Can you count the endpoints and describe where the figure continues?
Questions to Check Understanding
- Can you count the endpoints and describe where the figure continues?
- What in the numbers or diagram supports your answer?
Practice Advice
Work through the example together. Ask the learner to explain the first two problems, then try three independently. Review the first incorrect step before assigning more practice.
Next Practice
- Use New Numbers to practice the same skill with different values.
- If the learner needs help, return to the example and model each step before trying again.
