Because the center of curvature is defined to be in the direction of the normal. remember that a reflecting angle of light, relative to the normal, equals minus the angle of the beam that hit the mirror, relative to the normal. since the center of curviture is in the direction of the normal. A beam going through it would be with an angle of zero, and there for return with an angel of (minus) zero. In other words it comes back in the same direction.
The light ray passing from the centre of curvature is perpendicular or normal to the the sphere of which the concave mirror is a part . because the ray from centre to mirror will act as the radius and we know that radius is perpendicular to the tangent at the point of contact. hence angle of incidence = 0 degree , so angle of refraction will also be 0 degree , hence the ray will retrace its path .
when a ray of light strikes a solid surface , the light is not absorbed by it it is reflected back. this is reflected ray
The light ray passing through centre of curvature of a concave mirror is perpendicular to the sphere of which the mirror is a part. so it retraces its path

Concave mirror is used to a real image as big as real object. If the object is placed at center of curvature , then real image is formed at the same center of curvature.
Convex means rounded or curved like the exterior of a circle or sphere. Also called as fish eye or diverging mirror. The mirror coating of the concave mirror is on the outside of the spherical surface. In concave mirrors, the center of curvature and the reflecting surface fall on the same side of the mirror.

The focal length of a concave mirror is about equal to half of its radius of curvature.
10 cm from the mirror.

A concave mirror is a converging mirror used in microscopes and telescopes. Characteristics include forming real and inverted and diminished images when an object is placed beyond the center of curvature or real, inverted and enlarged image when the object is placed between the center of curvature and focus.

The most curved mirrors are spherical mirrors. The centre of curved surface is called center of curvature. There are two kinds of spherical mirrors. Concave and convex mirror.
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
