Yes it is. It's faces are different polygon shapes such as square, triangle, etc.... To see images and builds of polyhedrons go to this site: korthalsaltes.com
True.
No because they have many faces which is the meaning of the word polyhedron
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
The answer is a polyhedron
Any polyhedron other than a pyramid.
A three dimensional shape bounded by plane (flat) faces is a polyhedron.
All polyhedrons are three dimensional objects, with four or more faces, such as a pyramid.
pyramid
A tetrahedron (triangular pyramid).
if you mean common: one of the triangle, square, and pentagon vertion of pyramid, dipyramid, and gyrolongated dipyramid. a total of 9.
