What shapes do you need to make tetrahedron?
Four triangular faces.
What shapes does a tetrahedron have?
A tetrahedron is a four sided polyhedron. Each face is a triangle. If it is a regular tetrahedron, then each face is an equilateral triangle.
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.
Which 2D shapes will be required to make the net of a triangular pyramid?
It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
What 3D shapes have equilateral triangle faces?
A tetrahedron (4 faces) and an icosahedron (20).
What shapes do you need to make tetrahedron?
Four triangular faces.
What shapes does a tetrahedron have?
A tetrahedron is a four sided polyhedron. Each face is a triangle. If it is a regular tetrahedron, then each face is an equilateral triangle.
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 are Shapes of 4 congruent triangles?
Isosceles Tetrahedron.
What shapes are in a tetrahedron?
There are points (vertices) lines (edges) and polygons (faces).
List a few 3-d shapes?
Sphere, cuboid, tetrahedron.

What shapes have 4 vertices?
In 2 dimensions, a quadrilateral. In 3 dimensions, a tetrahedron.
Which 2D shapes will be required to make the net of a triangular pyramid?
It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
How many 3d shapes have 4 faces?
Just one: a tetrahedron or triangular pyramid.
Name the shapes with 5 sides?
Pentagon (and in 3d: triangular prism and tetrahedron.)
What 3D shapes have equilateral triangle faces?
A tetrahedron (4 faces) and an icosahedron (20).
