What are Shapes of 4 congruent triangles?
Isosceles Tetrahedron.
A shape with 4 faces except for tetrahedron?
There are no other shapes that have only four flat faces except for a tetrahedron, although the faces thatmake up the tetrahedron can be triangles of various shapes and need not be all identical.
What shapes do you need to make tetrahedron?
Four triangular faces.
What shapes are in a tetrahedron?
There are points (vertices) lines (edges) and polygons (faces).
List a few 3-d shapes?
Sphere, cuboid, tetrahedron.
3d shapes with 4 faces?
tetrahedron (triangle-based pyramid)
What is the formula of the tetrahedron?
There can be no formula for a tetrahedron since you have not specified what aspect the formula is supposed to calculate. Furthermore, although they are all triangular pyramids, tetrahedra can be tall, needle-like shapes or almost flat shapes.
Name the shapes with 5 sides?
Pentagon (and in 3d: triangular prism and tetrahedron.)
What shapes have 4 vertices?
In 2 dimensions, a quadrilateral. In 3 dimensions, a tetrahedron.
What 3D shapes have equilateral triangle faces?
A tetrahedron (4 faces) and an icosahedron (20).
How many 3d shapes have 4 faces?
Just one: a tetrahedron or triangular pyramid.
What shapes make a tetrahedron?
A tetrahedron is the smallest possible polyhedron: a closed 3-d shape with polygonal faces. It has 4 triangular faces, 4 vertices and 6 edges.
