What is the shape with each face as an equilateral triangle?
A four sided figure would be a tetrahedron and a 20 sided would be an icosahedron. They both have equilateral triangles for faces so your question is a little incomplete.
What shape can you make using four equilateral triangles?
A parallelogram.
How do you compare and contrast an equilateral triangle and a square?
Differences: Squares have 4 sides / equilateral triangles have 3 sides. Squares have 90 degree angles / equilateral triangles have 60 degree angles. Squares have 2 diagonals / equilateral triangles have none Similarities: All sides of the shape are congruent All angles of the shape are congruent
Is a triangle a symmetric shape yes or no?
Some triangles are symmetric, while others are not. All equilateral and isosceles triangles are symmetric.all triangles are symmetric.
What shape has 4 faces that are all triangles?
A triangle based pyramid.
What shape has 20 congruent equilateral triangles as faces?
An Icosahedron.
What 3d shape has 20 congruent equilateral triangles as faces?
An icosahedron.
What is name of a shape with twenty congruent equilateral triangles as faces?
This shape is called a Icosahedron , I think.
What is shape has 4 triangular face's?
The tetrahedron has 4 equilateral triangles as its faces.
Shape with four faces?
A three-dimensional figure or shape, such as a tetrahedron, has four faces. These faces are equilateral triangles. A tetrahedron also has four vertices and 6 edges.
How many faces do 6 triangles have meeting at each vertex?
That shape is a unit equilateral triangular dipyramid, and it has 6 faces.
Eight equal sides and faces are triangles?
A three-dimensional shape with eight triangular faces is called an octahedron.
How many faces does octahedron has?
In geometry, an octahedron (plural: octahedra) is a polyhedron with eight faces. A regular octahedron is a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.It is a 3-dimensional cross polytope (shape).---Wikipedia
Suppose you have an equilateral triangle. The area of the triangle is exactly 1200 square centimetres. Now suppose you have twenty of those triangles. It's possible to assemble those twenty triangles?
An icosahedron is a shape with twenty equilateral triangles as faces.
What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
Are all the sides of a octahedron equilateral triangles?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The faces of octahedra can be triangles, quadrilaterals, pentagons, hexagons or heptagons. There are many examples of octahedra - a hexagonal prism, for example - which has no triangular face. At the other extreme, all the faces of a regular octahedron are equilateral triangles.
What 3D shapes have triangular faces?
In geometry, a deltahedron (plural deltahedra) is a polyhedron whose faces are all equilateral triangles. The name is taken from the Greek upper case delta (Ξ), which has the shape of an equilateral triangle.
