The faces of a polyhedron are the polygons that form the polyhedrons surface true or false?
True.
Why do you need polyhedrons?
To study solid objects whose faces are all polygons.
Solids having flat surfaces that form into polygons are polyhedrons true or false?
true
How many faces vertices and edges does a rectangle have?
Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.
What has bases and sides that are polygons?
All polyhedrons.
Is a polyhedron a solid figure with faces that are polygons?
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
What polygon has three or more faces that are triangles with common vertex?
Polygons aren't normally described as having faces Polyhedrons are normally described as having faces So it could be a tetrahedron which is a triangular based pyramid
How the names of the polyhedrons help you to know the number of faces?
In the same way that knowing the names of polygons helps you to know how many sides it has. Polygon means many sides and polyhedron means many faces
Three dimensional figures made of polygons are called polyhedrons?
Yes.
What are all the shapes that are not polygons?
They are 3 dimensional objects such a s polyhedrons.
What is the properties of polyhedrons?
a polyhedron is any 3d figure with all flat polygons for sides(polygons have straight sides)
What are polhedrons?
Polyhedrons are shapes with many faces
