FREE Know the Value of Points Lines and Planes Worksheet [PDFs] - Free Printable

Let’s go step by step to solve this worksheet.

We are working with three basic geometry ideas:
- A line goes on forever in both directions. It has arrows on both ends. We can name it using any two points on it, like AB or BA — order doesn’t matter for lines.
- A ray starts at one point and goes forever in one direction. It has an arrow on only one end. When we name a ray, the first letter is always the starting point (the endpoint), and the second letter is another point on the ray. So Ray PQ means it starts at P and goes through Q.
- A line segment has two endpoints — it does NOT go on forever. It’s just the piece between two points. We name it using its two endpoints, like XY or YX — order doesn’t matter for segments.

Now let’s look at Part A: “Name each line, ray or line segment.”

We’ll examine each numbered figure:

1) This has two endpoints: S and T. No arrows → it’s a line segment. Name: ST or TS.

2) Starts at R, goes through S, and has an arrow past S → it’s a ray. Starts at R → so it’s Ray RS.

3) Has arrows on both ends, passing through V and W → it’s a line. Name: VW or WV.

4) Two endpoints: C and D → line segment. Name: CD or DC.

5) Starts at M, goes through N, arrow past N → ray. Starts at M → Ray MN.

6) Has arrows on both ends, passing through U and V → line. Name: UV or VU.

Now Part B: “Draw and label each of the following.”

We need to draw based on the notation given.

1) BC with a line over it → that means a line through points B and C. Draw a straight line with arrows on both ends, and mark points B and C somewhere on it.

2) YZ with a ray symbol (arrow over YZ, pointing right from Y) → that means a ray starting at Y and going through Z. Draw a point Y, then a point Z to the right of it, and an arrow going past Z. Label them.

3) QR with a segment bar over it → that means a line segment between Q and R. Draw two points, Q and R, connected by a straight line with no arrows. Label them.

✔ Let’s double-check:

Part A:
1) Segment → ST
2) Ray → RS (starts at R)
3) Line → VW
4) Segment → CD
5) Ray → MN (starts at M)
6) Line → UV

Part B:
1) Line through B and C → draw line with arrows, label B and C
2) Ray starting at Y through Z → draw from Y through Z with arrow past Z
3) Segment between Q and R → draw line between Q and R, no arrows

All correct!

Final Answer:
Part A:
1) ST
2) Ray RS
3) Line VW
4) CD
5) Ray MN
6) Line UV

Part B:
1) Draw a line with arrows on both ends, label points B and C on it.
2) Draw a ray starting at Y, going through Z, with an arrow beyond Z.
3) Draw a line segment connecting points Q and R (no arrows).
