congruence
The analogy for "square: triangle" is "cube: tetrahedron." Just as a square is a two-dimensional shape with four equal sides, a triangle is a three-dimensional shape with three vertices. Similarly, a cube is a three-dimensional shape with six equal square faces, while a tetrahedron is a three-dimensional shape with four triangular faces. Both pairs represent geometric shapes with increasing dimensions and different characteristics.
Such a shape does not exits. See the attached link for all 3d shapes with 6 plane faces.
a traingle can not have no sides, then it wouldnlt be a triangle, as far as i know, all 2d dimensional shapes have at least 3 SIDES, a shape with no sides isn't a shape, its nothing ness A scalene triangle- All sides are different
The shape of the 12 faces of a regular dodecahedron are regular pentagons.
circle, sphere and another shape do not have faces or edges
A triangle has only one face and, not surprisingly, its shape is a triangle.
Only one; a triangle is a 2D shape, not a 3D shape. Usually only 3D (or more) shapes are considered to have 'faces'.

There are infinitely many such shapes. A tetrahedron is one example.
Your shape is a triangular octagon. * * * * * What on earth is that shape? The most likely answer is an octogonal pyramid.
scalene triangle,circle,a polygon of iregular shape
Octohedron
Many shapes circle, equalateral triangle, square, and all normal shapes from then on such as pentagon and hexagon etc.
Pyramid
Oh, isn't that a lovely question! Shapes with an odd number of faces can be quite special. One shape that fits this description is a pyramid. It has a triangular base and three faces meeting at a single point, creating a total of four faces.
