• Cube- is a polyhedron whose six faces are all squares
• Rectangular parallelepiped is a polyhedron whose six faces are all rectangular.
• A prismis a type of polyhedron whose congruent bases lie in parallel planes.
• Right Prism– is a prism whose lateral faces or lateral edges are perpendicular to the bases.
• Regular Prism–is a right prism whose bases are regular polygon.
• Oblique Prism–is a prism whose lateral faces andlateral edges are not perpendicular to its bases.
• . Base – is the plane where the two-dimensional shape or polygon begins and ends.
• Lateral faces – is a surface on the sides of a prism or the non-base faces
• Lateral edges – is the intersection of lateral faces of a prism.
• Altitude/Height – is the distance between the bases.
• A lateral surface area (LSA) is the sum of the areas of the rectangularlateral faces.
• Polyhedron- is a solid bounded by planes.
• . Faces- are the portions of the bounding planes enclosed by the edges.
• Edges- are the intersections of the bounding planes in a polyhedron.
• Vertex/Vertices- are the intersections of the edges.
• Section- of a solid is the plane figure cut from the solid by passing a plane through it.
• A polyhedron is a three-dimensional figure that is formed by polygons that enclose a region in space.
• A prism is a polyhedron with two parallel, congruent bases. The other faces, also called lateral faces, are rectangles.
• Each polygon in a polyhedron is a face
• The line segment where two faces intersect is an edge.
• The point of intersectionof two edges is a vertex.
• examples of polyhedron - cube, prism, pyramid
• example of not polyhedron - sphere, cones and cylinder
• A regular polyhedron is a polyhedron where all the faces are congruent egular polygons.
• One way to “view” a three-dimensional figure in a two-dimensional plane is to use cross-sections
• A cross-section is the intersection of a plane with a solid
• A net is an unfolded, flat representationof the sides of a three-dimensional shape.
