WRONG
To determine which of the following options correctly describes a sphere, we need to understand the characteristics of a sphere.
A sphere is a three-dimensional geometrical figure that is perfectly symmetrical in all directions. It is defined by the set of points in three-dimensional space equidistant from a fixed point called the center.
Analyzing the options:
- "A sphere has a center" is correct, as mentioned earlier.
- "A sphere has a vertex" is incorrect. A vertex typically refers to a point where different edges or lines meet, but a sphere does not have any sharp corners, edges, or vertices.
- "A sphere has a face" is incorrect as well. Faces are flat surfaces, but a sphere is a curved surface with no flat faces.
- "A sphere has an edge" is incorrect. An edge refers to a line segment where two faces of a solid meet, but a sphere has no edges due to its continuous curvature.
Therefore, the correct option is "A sphere has a center."
