SOLID FIGURES SPI 3108.4.5

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.

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.

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

RECTANGULAR PRISM –CUBE- PRISMS RECTANGULAR PRISM –CUBE- TRIANGULAR PRISM PENTAGONAL PRISM

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

PYRAMIDS TRIANGULAR PYRAMID RECTANGULAR PYRAMID -TETRAHEDRON- PENTAGONAL PYRAMIDS

CONES AND CYLINDERS CIRCULAR PRISM -CYLINDER- CIRCULAR PYRAMID -CONE-

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.
