This worksheet helps students master basic geometry vocabulary by identifying figures and drawing specific line relationships.

Let's go through each part of the worksheet step by step, solving and explaining each problem with correct geometric terminology and symbols.

---

Part A: Name each figure in one way. Make sure to use correct symbols!

1. Figure: A line with points J, K, L, extending infinitely in both directions (arrows at both ends).
- This is a line passing through points J, K, and L.
- Since it extends infinitely in both directions, we name it using any two points on the line with a double-headed arrow over them.
- ✔ Answer: $\overleftrightarrow{JL}$ or $\overleftrightarrow{KL}$ or $\overleftrightarrow{JK}$ — all are acceptable.
Let’s pick: $\boxed{\overleftrightarrow{JL}}$

2. Figure: A single point labeled C.
- This is simply a point.
- ✔ Answer: $\boxed{C}$

3. Figure: A ray starting at D, going through E and F, with an arrow at F (indicating direction).
- This is a ray, starting at D and passing through E and F.
- The naming convention is: start point, then any other point on the ray, with a ray symbol (one arrow).
- ✔ Answer: $\boxed{\overrightarrow{DF}}$

4. Figure: A parallelogram with points F, G, H, W inside, and arrows indicating movement around the shape.
- This is a plane figure (specifically a parallelogram) with labeled points inside.
- But since the question asks to name the figure, and there are no lines drawn between the points, it appears to represent a plane (a flat surface), possibly with points located within it.
- However, given the arrows around the shape, this may be showing translation vectors. But based on standard geometry practice, if the entire figure is a quadrilateral with opposite sides parallel, it’s a parallelogram.
- But the instruction says "name the figure", so likely referring to the plane containing these points.
- ✔ Answer: $\boxed{\text{Plane } FGHW}$ (or just plane), but more precisely, since it's a 2D shape, we can say:
$\boxed{\text{Parallelogram } FGHW}$ — assuming vertices are F, G, H, W in order.

> Note: Without clear connections between points, it's ambiguous. But since it looks like a parallelogram with arrows indicating motion, the most reasonable interpretation is that it's a parallelogram named using its vertices.
> So: $\boxed{\text{Parallelogram } FGHW}$

5. Figure: Three points P, Q, R aligned vertically, with segments connecting them.
- This is a segment from P to R, with Q in between.
- We name it using endpoints with a segment bar.
- ✔ Answer: $\boxed{\overline{PR}}$ (since it's a straight line segment from P to R)

6. Figure: A line segment AB with an arrow pointing left from A, but not extending beyond B.
- Wait: only one arrow at A, and B is endpoint. So it's a ray starting at B and going through A? No — the arrow is at A, meaning it extends from B through A.
- Actually: the arrow is at A, and B is to the right. So the ray starts at B and goes through A and beyond? That would mean it's going from B → A → further left.
- But the arrow is at A, and B is on the right, so the ray starts at B and goes toward A and continues beyond.
- But the notation: the arrow is on the left end (at A), and B is on the right. So the ray starts at B and passes through A, extending beyond A.
- Wait — the arrow is at A, which is the left end. So the ray starts at B and goes through A and continues to the left.
- So the ray has endpoint B, and goes through A.
- ✔ Answer: $\boxed{\overrightarrow{BA}}$

Part B: Use vocabulary terms to answer each question

7. Name the angle in 3 ways.
- The angle is formed at point S, between rays SR and ST.
- There is a number label “5” near the angle.
- Ways to name an angle:
- Using three points: vertex in the middle → $\angle RST$
- Using vertex alone: $\angle S$
- Using number: $\angle 5$
- ✔ Answers:
$\boxed{\angle RST},\ \boxed{\angle S},\ \boxed{\angle 5}$

8. Draw a pair of parallel lines. Name them $\overleftrightarrow{EF}$ and $\overleftrightarrow{GH}$.
- Parallel lines never intersect and are always the same distance apart.
- Draw two straight lines that do not cross.
- Label one as $\overleftrightarrow{EF}$, the other as $\overleftrightarrow{GH}$.
- ✔ Drawing Instructions:
- Draw two horizontal lines, one above the other.
- On the top line, mark points E and F, and write $\overleftrightarrow{EF}$.
- On the bottom line, mark points G and H, and write $\overleftrightarrow{GH}$.
- Add arrows at both ends of each line.
- Ensure they are equidistant and don't intersect.

9. Draw an angle. Label it $\angle XYZ$.
- Draw two rays sharing a common endpoint.
- Label the vertex Y, one ray endpoint X, the other Z.
- The angle is formed at Y.
- ✔ Drawing Instructions:
- Draw a point Y.
- From Y, draw ray YX and ray YZ.
- Label the angle as $\angle XYZ$.
- You can also add a small arc between the rays.

10. Draw a pair of perpendicular lines that intersect at point L.
- Perpendicular lines intersect at a 90° angle.
- They must form a right angle at point L.
- ✔ Drawing Instructions:
- Draw a point L.
- Draw one line through L horizontally.
- Draw another line through L vertically.
- Add a small square at the intersection to indicate a right angle.
- Label the lines appropriately (e.g., line m and n, or just show the intersection at L).

11. Name the angle in 3 ways.
- The angle is at point D, between points C and E.
- Numbered “2”.
- Rays: DC and DE.
- So:
- $\angle CDE$
- $\angle 2$
- $\angle EDC$ (but usually vertex in middle)
- ✔ Answers:
$\boxed{\angle CDE},\ \boxed{\angle 2},\ \boxed{\angle EDC}$
(Note: $\angle EDC$ is acceptable, though $\angle CDE$ is preferred.)

12. Name the angle in 3 ways.
- Angle at point B, between points A and C.
- Numbered “6”.
- So:
- $\angle ABC$
- $\angle 6$
- $\angle CBA$
- ✔ Answers:
$\boxed{\angle ABC},\ \boxed{\angle 6},\ \boxed{\angle CBA}$
