It is a square or a rhombus
Since the number of sides and vertices is different, it cannot be a 2-dimensional shape. The only 3-dimensional shape with 4 vertices is a tetrahedron and that does not have 6 sides. Consequently, there is no such shape.
A common polygon with five vertices is the pentagon. A common three dimensional shape with five vertices is the square pyramid.
Two-dimensional, think of circles, ellipses... Three-dimensional: spheres, etc.
A three dimensional shape is where you have height, width, and length where as in a two dimensional shape you only have height and length
In 2 dimensional space: a heptagon In 3 dimensional space: a heptahedron.
2-dimensional shapes, with three straight sides have three vertices.
No, not all three-dimensional shapes have vertices. A vertex is an angle point of any shape. Spheres do not have vertices.
A two dimensional shape would have 17 sides. For a three dimensional shape - assuming that sides are faces - the answer depends on the shape itself.
There is no such shape as a regtangiel. If you meant a rectangle, that is a 2-dimensional shape with 4 vertices, 4 edges and one face.
then it's a - Dodecahedron
A nonagon is a two dimensional; figure with 9 vertices.
Two pairs of touching sides are the same length. The diagonals meet at right angles. Opposite sides are not parallel.
