Educational worksheet for identifying and labeling the parts of a circle.

Let me carefully examine the diagram to match each label with the correct part of the circle.

I see a circle with five arrows pointing to different parts:
- One arrow points to the outer curved line (the full boundary).
- One arrow points to a line from the center to the edge.
- One arrow points to a line passing through the center, connecting two points on the edge.
- One arrow points to a line connecting two points on the edge but not passing through the center.
- One arrow points to the middle dot inside the circle.

The available labels are:
- center
- radius
- chord
- circumference
- diameter

Now I’ll match them:

1. The outer curved line → circumference
2. The line from center to edge → radius
3. The line through the center, touching both sides → diameter
4. The line across the circle but *not* through the center → chord
5. The middle dot → center

Let me verify by zooming in on each arrow and its target to be sure.
