Prisms Pyramid Sphere Cone Cylinder
POLIHEDRONS
There are solid bodies that their faces are flat.
We can divided in 2 groups:
1. Prisms
2. Pyramids
PRISMSThey are polyhedrons that have:
a) 2 basal faces
b) Their lateral faces are flat.
We can divide them in 2 groups:
1.CUBE: All their faces are squares. It has 6 faces.1.RECTANGULAR PRISM, TRIANGULAR PRISM.
They depend of the shape of the basal face.
[pic]
PYRAMIDS
They are polyhedrons that have:
a) 1 basalface
b) Their lateral faces are flat.
Their names depend on the basal faces.

ROUND BODIES
We classified round bodies in 3 groups:
1. Cone: It has 1 basal face, 1lateral face or mantle and 1 vertex or apex.
2. Cylinder: It has 2 basal faces, 1 lateral face and 2 edges.
3. Sphere: It has no faces, no vertex and no edges.
