In 3d a hexagonal pyramid. In 2d, two hexagons. Or a six-pointed star (like a Star of David), a parallelogram plus lots more possibilities
if u are talking about polygons then u would get a hexagon
A hexagon is divided into 6 equilateral triangles; the circle around the hexagon has a radius the length of one of these triangles. So the circumference is S x 2pi, s being the side of the hexagon. The perimeter of the hexagon is 6s. So the relationship is that you multiply it by 1/3 pi
A square based pyramid

A Triangular Pyramid has 4 triangles and 1 square.

a hexagon * * * * * Depending on the shape and sizes of the triangles and where they are attached, you can also get a kite, a rectangle, a parallelogram, a decagon, octagon, pentagon.

A rectangular based pyramid would fit the given description

4 triangles make 1 hexagon. (easy way to find out how many triangles there are in a polygon- take number of sides of the polygon, subtract 2 from it, that's your answer!)

Almost any 2D/3D shape has more than one vertex. Triangles, squares, rectangles etc. etc.
