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.
how many more vertices does a square pyramid have that triangular pyramid
11 vertices (one more than the number of vertices in the base).
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.

Oh, dude, there are technically 35 triangles in a pentagon. You've got the main five triangles from the pentagon itself, then you can make 10 more by connecting each vertex to the other non-adjacent vertices, and finally, you can make 20 more by connecting each vertex to the midpoint of the opposite side. So, yeah, 35 triangles in total, if you're into that kind of thing.
