- 4Define: EdgeWhere two faces meet at a line
- 5Define: VerticesThe point of intersection of two edges
- 6Types of polyhedra: Regular Polyhedra (platonic solids)Faces are REGULAR polygons & congruent
- 7Types of polyhedra: Irregular PolyhedronIrregular polygonal faces & angles that are NOT congruent
- 8Classification: Prism (3)1. Three-dimensional solid
2. Identical faces (congruent polygons) at both ends
3. Same cross-section all along its length
*Named after its base & relationship (alignment) of the two bases to each other - 9Types of prism: Regular PrismBase of the prism is in the shape of a regular polygon
- 10Types of prism: Irregular PrismBase of the prism is in the shape of an irregular prism
- 11Prisms based on alignment: Right PrismTwo flat ends that are perfectly aligned with all side faces in the shape of rectangles
- 12Prisms based on alignment: Oblique PrismAppears to be tilted & the two flat ends are NOT aligned & the side faces are parallelograms
- 13Define: ParallelogramA quadrilateral with both pairs of opposite sides parallel
- 14Properties of a Pyramid *4 characteristics*1. Three main parts: apex, face & base
2. Polygon base most often a square
3. Faces of pyramid = lateral faces
4. Triangles are congruent & isosceles - 15Types of pyramids: Square Pyramid (Base, Face, Edge, Vertices & 4 Faces)Base: Square
4 triangular faces: 8 edges, 5 vertices & 4 faces - 16Types of pyramids: Triangular Pyramid (Base, Edge, Vertices & 4 Faces)Base: Triangle

6 faces, 6 vertices & 10 edges - 18Define: Right PyramidThe location of the apex is exactly over the middle of the base of the pyramid.
- 19Define: Oblique PyramidThe location of the apex is not exactly over the middle but slightly away.
- 20Define: Regular PyramidBase of pyramid is a regular polygon
- 21Define: Irregular PyramidBase is an irregular polygon + sides are not congruent
