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.
What solid figure has 4 equal sides the faces are triangle?
a pyramid, in the sense that most people think of has a square base, with 4 triangle 'sides', which would be 5 faces. A regular tetrahedron has 4 equilateral triangles as faces.
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.
