None. A vertex implies an angle which, in turn, implies at least two lines.
circle
they connect the shape together It all belongs to one shape
Vertices are points where two lines meet. For example, a square has 4 vertices. A cylinder is comprised of circles, so there is only one line [instead of two lines to meet], so there are no vertices.
need to see a pic of a shape with 4 sides and 3 vertices can you supply one
Technically, there's no shape with no surface and no vertices, but a sphere is close. It has no vertices but has just one surface.
A symmetrical shape is said to have line symmetry. A shape that has line symmetry can have one or more lines of symmetry
No. Every solid shape has at least one face. The closest you will get is a sphere, which has no edges or vertices, but it still has a face.
half a sphere
There is no such shape as a regtangiel. If you meant a rectangle, that is a 2-dimensional shape with 4 vertices, 4 edges and one face.
Yes, if its one corner it is called Vertex, but if its corners ,its called Vertices.
A line segment connecting two vertices of a polygon is called an edge if the vertices are adjacent to one another. Otherwise it is called a diagonal.
Any shape with two or more vertices can have one or more pairs of equal angles. The simplest of these is a symmetric lenticular shape with just two vertices.
