All triangles have exactly 3 vertices
There are a number of properties of two similar triangles. This includes having same vertices, they also have the same angles and so much more.
11 vertices (one more than the number of vertices in the base).
how many more vertices does a square pyramid have that triangular pyramid
A decagon can have eight or more triangles - up to infinitely many.

In two dimensions, all sorts of triangles. In 3 or more dimensions there is no specific name for shapes with three vertices.

A dodecahedron is a polyhedron with 12 faces. There are 6,384,634 topologically distinct convex dodecahedra with 8 or more vertices. A hexagonal bipyramid, a dodecadeltahedron, a triakis tetrahedron are examples of dodecahedra all of whose faces are triangles. There are many more dodecahedra in which some, but not all, faces are triangles.

There is no limit to the number of triangles. At any time, you can select a triangle; select one of its vertices and draw a line from that vertex to the opposite side. That gives one more non-overlapping triangle. And you can keep on doing that indefinitely.
