a solid formed by connecting the
Prism corresponding vertices of two
parallel congruent polygons.
Parallel and
congruent
polygons
Parallelograms
(if all Lateral Faces are
Rectangles, it is a
Right Prism)
Classify this prism.

Surface Area of a Prism
The default "game plan" for finding
Surface Area in any solid is to find the
area of each "face" separately and then
add up those measurements.
Surface Area of a Prism
When the prism happens to be a right
prism or a right prism with a regular
base we can develop "short cut"
formulas.

Pyramid-
February 18-19, 2016
a solid that features a polygon base with
triangular lateral faces that share a side
with each side of the base and the lateral
faces share a common point called a
vertex.
Pyramid A Pyramid is "Regular" if:
1. Base is a Regular Polygon
2. All Lateral Faces are congruent
isosceles triangles
