To provide you with the precise definition of the figure in the image, I would need to see the image itself. However, based on the options you've provided, here are the definitions:
- A part of the circumference of a circle or other curve - This typically refers to an arc.
- The finite section of a line between two points on that line - This defines a line segment.
- The figure formed by two lines extending from the same point - This describes an angle.
- A line that connects two points - This also refers to a line segment.
If you can describe the figure in the image or provide more context, I would be happy to help identify the correct definition.
