Can you name the 3-dimensional shape with 20 congruent triangles as faces?
It is called an Icosahedron. An example could be the 20-sided die, if you have seen those before.

If the triangles are congruent then it is a triangular-based prism.
yeah umm its called an iscohedron! i reckon its quite hard to spell! i luv cows so much cya later good luck with stuff! from somebody i cant say just to be sure. mwahahaha
This shape is called a Icosahedron , I think.
Isosceles Tetrahedron A solid with four faces is a tetrahedron. Each of the faces is atriangle. If all the triangles are congruent, you have an isoscelestetrahedron.
A hexagon based pyramid.
square based pyramid
yes there are shapes called 3 congruent figures
A cube, rectangular prism, or pyramid.
A triangular prisim (3 faces on sides, one face on bottom).
An icosahedron is a regular polyhedron with 20 equilateral triangle faces.
There are a few families of polyhedra with identical faces. There are none whose faces have 6 or more sides. There is no special name for polyhedra whose faces are pentagons… or pentagrams. A dodecahedron is an example. If coplanar faces are disallowed, the only polyhedron with quadrilateral faces are the cube and rhombohedron. There are infinitely many polyhedra with equilateral triangular faces: the tetrahedron, octahedron and icosahedron are examples.
It is a triangular prism
You are a triangular based pyramid (tetahedron) with 4 faces, 6 edges and 4 vertices.
