What is a Platonic solid with 4 faces?
A tetrahedron is known as a triangular pyramid in geometry. The tetrahedron consists of 4 triangular faces, 6 straight edges, and 4 vertex corners. It is a platonic solid which has a three-dimensional shape with all faces as triangles.

How many regular polyhedra are there?
five regular polyhedra
Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron. Pythagoras (c. 580–c. 500 bc) probably knew the tetrahedron, cube, and dodecahedron.
Which shape has 4 faces 4 vertices and 6 edges?
tetrahedron
The smallest polyhedron is the tetrahedron with 4 triangular faces, 6 edges, and 4 vertices.
Can a polyhedron have 4 faces?
A polyhedron has to have a minimum of four faces. (ii) Yes, a polyhedron can have four triangles which is known as a pyramid on a triangular base. Because all the edges are meeting at the vertices. (iii) Yes, a polyhedron has its faces a square and four triangles which makes a pyramid on a square base.
What is the model of Plato?
Plato’s Theory of Forms: Plato believed that there exists an immaterial Universe of `forms’, perfect aspects of everyday things such as a table, bird, and ideas/emotions, joy, action, etc. The objects and ideas in our material world are `shadows’ of the forms (see Plato’s Allegory of the Cave).
What kind of solid has 6 square faces?
1 Tetrahedron. In geometry, a tetrahedron is known as a triangular pyramid. 2 Cube. Cube is a solid three-dimensional figure with 6 square faces, eight vertices, and 12 edges, in geometry. 3 Octahedron. An octahedron is a polyhedron with eight faces, twelve edges, and six vertices in geometry. 4 Dodecahedron. 5 Icosahedron.
How many faces does a Platonic solid have?
Platonic solids have identical faces to regular polygons. There are five polyhedrons. Hexahedron or cube with six square faces. The table below shows the properties of platonic shapes: (EL = edge length) It has 6 faces, each with 4 edges (and is a square).
How many convex polyhedra have the same number of faces?
faces are made up of congruent regular polygons; the same number of faces meet at each vertex. There are nine regular polyhedra all together: five convex polyhedra or Platonic solids
Can a solid shape have more than one face?
Solid shapes can have more than one face. An edge is a line segment on the boundary joining one vertex (corner point) to another. They serve as the junction of two faces. A point where two or more lines meet is called a vertex. It is a corner. The point of intersection of edges denotes the vertices. “Solid shapes are fat, not flat.
