3D BODIES (Lucía, Nahia eta Alain)

The text discusses the classification of 3D shapes, focusing on polyhedrons and revolving bodies. Polyhedrons are divided into regular and irregular categories. Regular polyhedrons, also known as Platonic solids, include the tetrahedron, cube, octahedron, dodecahedron, and icosahedron, each characterized by faces that are regular polygons.

3D BODIES (Lucía, Nahia eta Alain)

FLAT FACES

Polyhedron (A solid shape with four or more flat surfaces.)
Irregular (A polyhedron with at least one irregular face.)

Prisms (A solid shape with flat sides and two bases that are the same shape.)

Pyramid (A polyhedron of which one face is a polygon (the base) of any number of sides and the other faces are triangles with a common vertex (the apex))

Regular (A polyhedron with all the faces regular polygons.)

Archimidean

Subtopic

Platonic bodies (Regular bodies with the same types of faces)

5- icosahedron (20 triangles)

4- dodecahedron (12 pentagons)

3- octahedron (8 triangles)

2- cube/hexahedron (6 squares)

1- tetrahedron (4 triangles)
