Corners of a solid shape are called its edges.

Explanation:
Solid shapes are three-dimensional objects that have length, width, and height. They are also known as 3D shapes. Examples of solid shapes include cubes, rectangular prisms, pyramids, spheres, cylinders, and cones.

Solid shapes have various features that help us identify and describe them. These features include faces, edges, and vertices.

- Faces: The flat surfaces of a solid shape are called its faces. For example, a cube has six square faces, and a pyramid has triangular faces.

- Vertices: The points where the edges of a solid shape intersect are called its vertices. For example, a cube has eight vertices, and a pyramid has a vertex at the top.

- Edges: The lines or line segments where the faces of a solid shape meet are called its edges. Each edge connects two vertices. For example, a cube has twelve edges, and a pyramid has several edges depending on the number of faces it has.

When we refer to the corners of a solid shape, we are talking about the points where its edges meet. These corners are called vertices, not edges.

Therefore, the correct answer is option C: Edges.

Vertice: The points where the edges of a solid shape intersect.
Edge: The lines or line segments where the faces of a solid shape meet.
Face: The flat surfaces of a solid shape.
