1.
altitude: segment joining both faces and ⊥ to both; used interchangeably w/ height
2.
Area of a sphere (A): TA=4πr²
3.
bases: lie in || planes and are ≅ polygons
4.
circle of intersection: intersection of a plane and a sphere
5.
formula for Lateral Area of prisms: LA=ph (p=perimeter of base, h=height of prism)
6.
height: length of altitude; used interchangeably w/ altitude
7.
Lateral Area (LA): sum of the areas of the lateral faces
8.
Lateral area of a cone (LA): LA=πrl
9.
Lateral area of cylinder (LA): LA=2πrh (r=radius, h=height of cylinder)
10.
Lateral Area of regular pyramid: LA=nF (n=number of faces, F=area of face)
LA=½pl (p=perimeter of base, l=slant height)
11.
lateral faces: parallelograms that intersect each other in parallel segments callled lateral edges
12.
regular pyramid: has a regular polygon as its base
13.
slant sleight (cursive l): altitude of lateral faces
14.
three properties of a regular pyramid: 1. all lateral faces are isoceles ∆s 2. all lateral edges are congruent 3. the altitude of the pyramid meets the base at the center of the polygon
