It's the adjective form of the word polyhedron, which means a solid figure with many plane faces, typically more than six.
NO
They are the plane surfaces which are bounded by edges of a solid object.
There is no polyhedron that meets these requirements. But there are many possible non-polyhedral shapes: for example, a hemisphere, a cone, a torus (doughnut) sliced by a plane perpendicular to its axis.
A trapezium is a plane shape and so has only one surface.
No- A square is a plane figure- it is a type of polygon not a polyhedron.
The wings of an airplane are near-flat surfaces that plane the air.
polyhedral
The tree is called a plane tree, and the machine is called a plane or a planer. Both are used in woodworking to smooth and shape wood surfaces.
Coplaner surfaces are two or more surfaces that are in the same plane.
It's the adjective form of the word polyhedron, which means a solid figure with many plane faces, typically more than six.
one
One.
None. There is one curved suface but no plane surface.
A icosahedron is a polyhedron with 20 plane surfaces.
A mineral that breaks along a weakly bonded plane is called "cleavage". Cleavage is the tendency of a mineral to break along smooth, flat surfaces determined by its internal atomic structure.
The force that pulls a plane up is called lift. Lift is generated by the wings of the plane as it moves through the air, creating a pressure difference between the upper and lower surfaces of the wings.
