all coplanar points equidistant from a given point
piece of a line with two endpoints
two rays with a common endpoint
piece of a line with one endpoint
line segment
circle
ray
angle

Explanation:

1. A circle is defined as all coplanar points equidistant from a given point.
2. A line - segment is a piece of a line with two endpoints.
3. An angle is formed by two rays with a common endpoint.
4. A ray is a piece of a line with one endpoint.

Answer:

1. all coplanar points equidistant from a given point -> circle
2. piece of a line with two endpoints -> line segment
3. two rays with a common endpoint -> angle
4. piece of a line with one endpoint -> ray
