A vertex.
I'm waiting for the answer
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 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 square, a rectangular solid
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. :)
true
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.
