A decagon. A two-dimensional shape (plane figure, or polygon) which has ten sides is a decagon. A three-dimensional shape (polyhedron) which has ten sides (plane faces) is a decahedron.
A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
It is a three-dimensional shape with twelve faces.
Three dimensional objects have edges, vertices and faces. A face is a plane surface which forms a boundary of the shape. Two faces meet along a line which is an edge. Three or more faces meet at a point which is a vertex.
decahedron
Pyramid
A tetrahedron, also called a pyramid is a three-dimensional shape with four faces.
No, a square is a two dimensional plane figure.
