Solids
2
Prisms A right prism has 2 parallel and congruent polygons called
the bases. Has rectangular lateral faces that are perpendicular with the bases. The lateral edges are parallel, congruent and perpendicular to the bases.
3
Vertex (where edges meet)
base Lateral face Lateral face edge edge
4
How many lateral faces:
How many edges: How many vertices How many bases The number of lateral faces is the same number as the sides of the base. The length of the lateral faces is equal to the perimeter of the base.
5
Pyramids apex Apothem or slant height (outside) Height (inside) base
6
Pyramids: Has only 1 base Has an apex at the top Lateral sides are made of triangles Height is on the inside from the center of the base to the apex Apothem is on the outside from the apex to the center of one side of the base The number of lateral triangles is equal to the number of sides on the base Pythagoras will be used frequently to solve problems
7
CYLINDERS BASE RECTANGULAR LATERAL FACE BASE
HEIGHT OF THE CYLINDER BASE THIS EDGE = CIRCUMFERENCE OF THE CIRCULAR BASE
8
CYLINDERS 2 BASES THAT ARE CIRCLES
THE CIRCUMFERENCE OF THE CIRCLE IS EQUAL TO THE WIDTH OF THE LATERAL FACE THE BASES ARE PARALLEL TO EACH OTHER
9
CONES apex Apothem (outside) “slant height” Height (inside)
Base is a circle
10
Cones have only 1 base the curved surface is called the lateral surface the height is inside the slant height is on the outside. the net of the cone is made up of a sector of a circle and a circle The edge of the sector = circumference of circle
11
Sphere every point on the surface is equidistant to the center Draw the net of a sphere. There is no net..it requires 2 separate pieces to create a sphere. A sphere has: no base
