All triangles have exactly 3 vertices
All pyramids are three-dimensional shapes. The number of vertices depends upon the shape of its based, which doesn't have to be a square or rectangle. The number of vertices is equal to n+1 , where n is the number of sides in the base polygon.
no
A polygon can have three or more edges and exactly the same number of vertices. All polygons have one face.
no
If you count all the corners (vertices), That is five!

Not exactly. A frustum would be a pyramid with the apex cut off. A truncated pyramid would be a pyramid with all vertices cut off.
no
For all polyhedra: vertices + faces = edges + 2 The given fact is: edges = vertices + 10 → vertices + faces = vertices + 10 + 2 → faces = 12
Most 2 dimensional shapes (all polygons) have 3 or more vertices. Most 3-dimensional shapes (polyhedra) have 4 or more vertices.
There are more than 8 square based pyramids, so it is not clear which ones you are thinking of.
In two dimensions, all sorts of triangles. In 3 or more dimensions there is no specific name for shapes with three vertices.
vertices is just a more complicated way of saying corners So if you count all the corners of a cube they equal 8

A triangular pyramid is one with a triangle shaped base and triangular sides (4 sides, all of them identical), therefore it would only have 6 edges and 4 vertices There are eight edges in a triangular pyramid, and there are five vertices on a triangular pyramid. Edges are the places where two flat surfaces meet. Vertices are the places where three or more flat surfaces meet. * * * * * The sides of a triangular pyramid need not be identical.
