enneahedron
Solid 3D figures are called polyhedrons. To figure out what a polyhedron with a specific number of sides is, you take the Greek prefix for the number of sides, and add the suffix "-hedron" at the end: tetra=4, so it would be called a tetrahedron if it has 4 sides. penta=5, so pentahedron. hexa=6, hepta=7, octa=8, ennea=9, deca=10 So your figure would be called a decahedron. I hope this helps ^-^ ~제니치
No, it is a plane figure.
A plane figure has 2 dimensions (length & width$ & is represented by a flat surface. It takes 3 noncollinear points to make a plane. A solid figure has 3 dimensions. It not only has length & width but also depth. It takes 4 noncoplaner points to make space
A solid figure with twenty faces is called an Icosahedron.
A side of a solid figure is called a face.
Decagon, if a plane figure or decahedron, if a solid.
true
A plane
The plane.
A solid has a depth, a plane figure does not.

Yes and no. Yes = plane figure No = solid figure.
A solid figure.
2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
No it is not a plane but it is a solidfigure
