1. 10.1 Vocab Day 1
Grab a notes page from the back under Geometry on Wednesday
Have notebook and homework out

2. Polyhedron
Polyhedron: a solid formed by polygons that enclose a single region of space
Regular Polyhedron: each face is enclosed by a regular polygon and each face is congruent and the faces meet at each vertex in exactly the same way
*Classified by number of faces with an exception of tetrahedrons; a polyhedron with four faces
Faces: the flat polygonal surfaces of a polyhedron
Edge: A segment where two faces intersect
Vertex: point of intersection of three or more edges
Edge
vertex

3. Prism
Prism: a special type of polyhedron, with two faces called bases, that are congruent and parallel polygons
The other faces are called lateral face, are parallelograms that connect the corresponding sides to the bases
Lateral faces meet to form lateral edges
*Classified by their bases

4. Right prism: a prism with rectangles as the lateral faces
Oblique prism: a prism that is NOT a right prism
Altitude of a prism: is any perpendicular segment from one base to the plane of the other base
*This is the height of the prism

5. Cylinder
Cylinder: one solid with curved surface with two circles as bases that are congruent and parallel
Axis: segment connecting center of bases
Radius: radius to the base
Right cylinder: axis is perpendicular to bases
Oblique cylinder: a cylinder that is NOT a right cylinder
Altitude of a cylinder: is any perpendicular segment from one base to the plane of the other base
*This is the height of the prism

7. Pyramid
vertex
Lateral face
Lateral edge
Pyramid: only one base and lateral faces all meet at common vertex
*altitude is the perpendicular segment from vertex to the plane of the base

8. Cone: solid with curved surface, one base, and a vertex
Right cone: vertex to center of base is perpendicular
Oblique cone: not a right cone
vertex
altitude
radius
base

9. Sphere
Center
Sphere: curved surface all points equal distance from the center
radius

10. Hemisphere: exactly half of a sphere
Center
Great circle: closes base of hemisphere
radius
