There are 4 triangles that make up a pyramid. 4 on the sides and on the bottom a square or rectangle.
The only thing I can come up with would be a tetrahedron. You could make a pyramid with a square (open) base, I guess.
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
pentagons and triangles-if i'm right, you get to answer this :Dwhat is a+b(4-2)if a=-6, if b=8it's easy, dont worry.

Five. Four triangles and one square make up a square pyramid.
Triangles (four of) and a square.One square as base and four triangles as sides.
a pentagonal pyramid is a shape with a base of a triangle, and triangles forming up to the point

27 triangles make up an Icosihenagon

3 triangles make up a hexagon.

The geometric term would be trigonal bipyramidal. It's basically a pyramid with another pyramid attached to its base, made up of equilateral triangles.
The shape that has a net that contains triangles could be a triangular pyramid. If you draw a triangular pyramid or get the shape of it, you can see that there are 4 triangles in the shape. I hope this answer helped you. If not, then i hope you find it. I really didn't get the question but i think my answer could help. You can search it up on google "Triangular Pyramid" and see the shape and also get an image of what i meant.
