i need to make a 14 sided figure from straws and pipe cleaners
Not sure what a decagonal is. Since the question refers to faces, edges and vertices, it may be assumed that the object in question is 3-dimensional. A decagon certainly is not, so decagonal cannot be a mistaken name for a decagon.
There is no such thing as a 3-D decagon.
3-dimensional
solid shapes are 3-D
In 2-d, the naming of polygons is such that a 10 sided shape is a decagon. Even if it is a 5-pointed star shape, it is a decagon. A concave decagon (rather than convex) but still a decagon. In 3-d, a decahedron, possibly, with the term "sides" being used for "faces".
No, because it is a 2 dimensional shape
A plain sided, 2-dimensional figure of TEN(10) sides. NB From the Latin roots, then names of polygons are :- 3 = tri 4 = tetra/quad 5 = pent 6 = hexa 7 = hepta 8 =- octa 9 = nona 10 = deca (As in decagon above).
A polygon (2-dimensional shape) with 10 sides is a decagon. A 3-dimensional polyhedron with 10 faces is a decahedron.
A 10-sided shape is known as a decagon.(A decahedron is a 3-dimensional solid with 10 polygonal faces.)

A triangle is a 3 sided shape. There are a few types, Isosceles, Scalene (Acute and Obtuse), Equilateral and the Right angle triangle.
A decagon has 7 more sides than a triangle. A triangle has 3 and a decagon has 10.
I'm getting a new Tetra for my aquarium. I am unfamiliar with the Tetra species. I already have a Cardinal Tetra, plus some Neons. The Flame Tetra is featured on a postage stamp from Cuba.
