What makes a solid a regular platonic solid?
A Platonic solid is a solid all of whose face are regular and congruent polygons.There are five of these:A Tetrahedron. Four faces, each an equilateral triangle.Ad InfoA Hexahedron (Cube). Six faces, each a square.An Octahedron. Eight faces, each an equilateral triangle.A Dodecahedron. Twelve faces, each a regular pentagon.An Icosahedron. Twenty faces, each an equilateral triangle.
Is a cylinder a platonic solid?
No. All the faces of a Platonic solid are identical regular polygons.
What solid figure would two equilateral triangles and three rectangles?
A net has two equilateral triangles and 3 rectangles. What solid figure might it make?
How many equal sides does a tetrahedron have?
In geometry, a tetrahedron is a solid with four faces, which is a triangular pyramid (don't forget the base-face), and a regular tetrahedron has (4) faces that are equilateral triangles.
The only Platonic solid with less than five faces is what?
tetrahedron
Platonic solid has eight faces that are equilateral triangles?
It is a regular octahedron.
What are the three types of polygons that can be the faces of a Platonic solid?
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
What has 8 congruent equilateral triangles as faces and 6 vertices?
A solid with 8 faces is an octahedron.As all faces are the same it is a regular octahedron.As such it is one of the five platonic solids - the only five 3D objects that can be regular: the tetrahedron (4 equilateral triangles for the faces), the hexahedron (usually called a cube with 6 square faces), the octahedron (as asked, 8 equilateral triangles for the faces), dodecahedron (12 regular pentagons as faces), icosahedron (20 equilateral triangles as faces).
What are the three type of polygons that can be a platonic solid?
Equilateral triangles, squares, regular pentagons.
Other than squares the polygons that can be the face of a Platonic solid are and?
equilateral triangles and regular pentagons
What shape has 8 congruent equilateral triangles as faces and 6 vertices?
The Platonic solid known as an octahedron would fit the given description

What solid has 4 faces which all are equilateral triangles?
It is a tetrahedron pyramid
What octahedron triangle for all their faces?
A regular octahedron is a Platonic solid with equilateral triangles for each of the faces. A heptagonal pyramid is an octahedron with one heptagon (a seven sided figure) as its base and 7 triangles, one attached to each side, meeting at the either vertex.
Name a solid that has 4 faces all of which are equilateral triangles?
A tetrahedron
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
What is an octahendron?
Well a Regular Octahendron is simply a platonic solid composed of 8 equilateral triangles, four of which meet at each vertex.
