Circle vocabulary worksheet with labeled geometric elements.

Since I can't view or access uploaded images directly, I can’t see the specific diagram you're referring to. However, based on your description and the typical structure of such a circle vocabulary worksheet, I can help you solve and explain the problem using standard circle geometry terminology.

Let’s assume the image shows a circle with labeled points and lines as described in the worksheet. Here's how to fill out the form correctly:

Circle Vocabulary Worksheet – Completed

Use color to label the picture.

#### Center:
- P
*(The center is the point equidistant from all points on the circle. In this case, it's labeled as P.)*

#### # of Radii:
- 3 (or more, depending on the diagram)
*(Radii are line segments from the center to any point on the circle. Examples: PA, PB, PC, PD, PT, PS, etc. If there are three such segments shown, then answer is 3.)*

#### Diameter:
- AX
*(A diameter is a chord that passes through the center. AX goes through P, so it's a diameter.)*

#### # of Diameters:
- 1
*(Only one diameter is clearly drawn: AX. Other chords may not pass through the center.)*

#### Chord:
- BC
*(A chord is a line segment connecting two points on the circle. BC connects B and C, both on the circle.)*

#### Secant Line:
- Line BD
*(A secant line intersects the circle at two points. Line BD passes through B and D, both on the circle.)*

#### Tangent Line:
- Line RA
*(A tangent touches the circle at exactly one point. Line RA touches the circle at point A.)*

#### Point of Tangency:
- A
*(This is the point where the tangent line touches the circle — in this case, point A.)*

#### Arc:
- Arc AB
*(An arc is a portion of the circle between two points. For example, arc AB is part of the circle from A to B.)*

#### Minor Arc:
- Arc AB
*(A minor arc is less than 180°. Arc AB is likely smaller than a semicircle.)*

#### Semicircle:
- Arc AXB (or Arc ATX, depending on labeling)
*(A semicircle is half the circle, formed by a diameter. Since AX is a diameter, the arc from A to X passing through B or T would be a semicircle.)*

#### Major Arc:
- Arc ACB (or Arc ATXBA, depending on the diagram)
*(A major arc is greater than 180°. It's named with three points: start, middle, end. Example: Arc ACB goes from A to B via C, which is longer than the minor arc.)*

✔ Summary of Key Definitions:

| Term | Definition | Example |
|------|-----------|--------|
| Center | The central point of the circle | P |
| Radius | Segment from center to edge | PA, PB, etc. |
| Diameter | Chord through center (twice radius) | AX |
| Chord | Any segment connecting two points on circle | BC |
| Secant Line | Line that intersects circle at two points | Line BD |
| Tangent Line | Line touching circle at one point | Line RA |
| Point of Tangency | Where tangent touches circle | A |
| Arc | Portion of circle between two points | Arc AB |
| Minor Arc | Less than 180° | Arc AB |
| Semicircle | Exactly 180°, formed by diameter | Arc AXB |
| Major Arc | Greater than 180° | Arc ACB |

🔧 How to Label the Picture:

- Use red for radii (e.g., PA, PB)
- Use blue for diameter (AX)
- Use green for chords (BC)
- Use purple for secant line (BD)
- Use orange for tangent line (RA)
- Use yellow for arcs (label them with curved arrows)

⚠️ Note: If your diagram has different labels or more elements, adjust accordingly. For instance:
- If CT is a diameter, then CT is also a diameter.
- If PW is a radius, label it as such.
- Always check if a line passes through the center (diameter), or just connects two points (chord).

If you can describe the exact points and lines in your diagram (e.g., “there’s a line from B to D passing through the circle”), I can give a more precise answer!
