What else can I help you with?
Are there any quadrilaterals that are 3D?
"Quadrilateral" means "four sides" and normally would be applied to plane, ie 2D, figures. Four-sided 3D figures are normally referred to as tetrahedrons, (properly tetrahedra) eg a three sided pyramid and its base.
What is a 3d quadrilateral with one pair of parallel sides?
A quadrilateral is a plane or 2d figure with four sides. A 3d shape (object) has a name ending with -hedron, eg a tetrahedron which is a four sided 3d shape. A 3d quadrilateral has no meaning. Sides (edges) do exist in 3d shapes, but a more pertinent attribute is faces. Do you mean by "3d quadrilateral" a 3d shape which has a quadrilateral as a base and at most 4 or 5 other sides, ie a pentahedron (usually called a square pyramid) or a hexahedron (some types of which are called cuboids and cubes)? Please re-ask using consistent terminology, eg What is a 3d shape with one pair of parallel faces and 6 faces?
What is the name of the twenty sided shape?
A two-dimensional shape with twenty sides is an icosagon. A three-dimensional object with twenty sides is an icosahedron.
Are there any type of 12 sided shapes?
Yes eg dodecagon
What number does deca stand for?
10. Eg decagon is a 10-sided polygon.
What 2D shape has a pair of parallel sides?
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
What are shape faces?
A shape face is basically a face on a shape eg: there are 6 faces on a cube and cuboid so there is your answer!
Does a regular shape has equal sides?
no a regular shape is the well known form of that shape eg: a square is a regular quadrilateral
What is a Alterego?
it is a two sided person. he or she has one side for eg. family and friends and one side for when hes a superhero
Why is a teabag a membrane?
Because it is a barrier (=it doesn't allow tea particles to get out of the teabag, it keeps the shape). Also, note it is selectively permeable = it allows some things to get in and out (eg water), but not others (eg tea particles).
What are the four kinds of real numbers?
Integers (eg 5), rational numbers (eg 7/9), irrational numbers (eg sqrt(3), transcendental numbers (eg π).
Who invented cube shape?
The cube shape occurs naturally in nature (eg a crystal of Galena is cubic) thus the shape was not invented by anybody.
