Labeling parts of a circle worksheet with terms and arrows pointing to corresponding features.

To solve the problem of labeling the parts of the circle in the provided image, we need to identify and label each part correctly based on its definition. Here is a step-by-step explanation:

Definitions of Circle Parts:

1. Center: The point inside the circle that is equidistant from all points on the circle.
2. Radius: A line segment connecting the center of the circle to any point on the circle.
3. Chord: A line segment connecting any two points on the circle.
4. Diameter: A chord that passes through the center of the circle. It is the longest chord and is twice the length of the radius.
5. Circumference: The distance around the circle (its perimeter).

Labeling the Image:

Let's analyze the image and assign the correct labels to each part:

#### 1. Top Horizontal Line:
- This line connects two points on the circle and passes through the center.
- Label: Diameter

#### 2. Vertical Line:
- This line connects two points on the circle but does not pass through the center.
- Label: Chord

#### 3. Line from Center to Edge:
- This line starts at the center and ends at a point on the circle.
- Label: Radius

#### 4. Curved Arc:
- This is the boundary of the circle.
- Label: Circumference

#### 5. Point in the Middle:
- This is the central point of the circle.
- Label: Center

Final Labels:

- Top horizontal line: Diameter
- Vertical line: Chord
- Line from center to edge: Radius
- Curved arc: Circumference
- Point in the middle: Center

Final Answer:

\[
\boxed{
\begin{array}{c}
\text{Top horizontal line: Diameter} \\
\text{Vertical line: Chord} \\
\text{Line from center to edge: Radius} \\
\text{Curved arc: Circumference} \\
\text{Point in the middle: Center}
\end{array}
}
