I'm waiting for the answer
A closed three-dimensional figure formed by four or more polygons that intersect only at their edges is called a polyhedron. It contains flat faces, straight edges, and sharp corners or vertices.
a square, a rectangular solid
vertex
Polyhedron is a geometric solid in three dimensions with flat faces and straight edges.
VERTEX
A vertex.
That is the Vertex
A solid figure with nine edges is a triangular prism. This shape consists of two triangular bases and three rectangular lateral faces. The edges include three edges from each triangular base and three connecting edges between the bases, totaling nine edges.
A solid figure with nine edges is known as a triangular prism. It consists of two triangular bases connected by three rectangular faces, resulting in a total of nine edges: three edges from each triangular base and three edges connecting the corresponding vertices of the triangles.
A vertex is the point where three or more edges of a solid figure meet.
A basic pyramid with three sides?
A closed three-dimensional figure formed by four or more polygons that intersect only at their edges is called a polyhedron. It contains flat faces, straight edges, and sharp corners or vertices.

A tetrahedron is a polyhedron with four triangular faces, six edges, and four vertices. It is a three-dimensional shape formed by connecting four equilateral triangles at their edges, resembling a pyramid with a triangular base.
A vertex on a cube, for example, is where any three edges meet. On a pyramid (square type) it could be at the point on the top or the 4 bottom edges. :)
The point where three or more edges of a 3D figure meet is called a vertex. In geometric terms, a vertex is a fundamental component of polyhedra and other solid figures, serving as a corner or a junction point for the edges. Each vertex can be connected to other vertices by edges, forming the overall shape of the solid.
