1. SOLID FIGURES
SPI

2. Solid Figures Solids enclose a part of space (3 dimensional or 3D).
Solids with flat surfaces that are polygons are called POLYHEDRONS.
There are two types of Polyhedrons called PRISMS and PYRAMIDS.

3. Solid Figures The 2-dimesional surfaces are called FACES.
Two faces intersect in a segment called an EDGE.
The 2-dimesional surfaces are called FACES.
Three or more edges intersect at a point called a VERTEX.

4. PRISMS
A solid figure with two parallel faces called BASES. The two bases are connected by polygons called LATERAL FACES.

6. PYRAMIDS Vertex Lateral Faces Base
A solid figure with one base and the lateral faces meet at a common point called the VERTEX.

9. PLATONIC SOLIDS
PLATONIC SOLIDS are special polyhedrons in which all the sides are the same.
Cube – all faces are squares.
Tetrahedron – all faces are triangles.
