An angle is formed when two rays meet.
In 2 dimensional space, a vertex is formed when two lines meet at an angle. In 3D space, a vertex is a point where three or more faces meet.A sphere is not an arced line but is one curved surface. It has no vertex.
A tube is a type of cylinder, which has two circular faces, one at each end. It also has three edges - two circular edges around the faces and one curved edge around the side. A tube has no vertices, as vertices are defined as the points where edges meet, and a tube's edges do not meet at any points.
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.

As long as they are not parallel, they will meet at an "edge", which is just a straight line.
If the faces are flat, it's a line.

A cube has 6 faces, 12 edges, and 8 vertices. Each face of the cube is a square, and it is formed where the edges meet. The edges connect the vertices, which are the points where the corners of the cube meet.
