1. Cross Sections
SWBAT: Describe the two-dimensional figures that result from slicing three-dimensional figures with a plane.

2. In a prism, and at times in cylinders the shape is made by stacking several figures on top of each other that are ________________ .
If you stacked the same shape as the base, except that it is a little smaller each time until they reached a point at the top, you will create what is known as a______________.
These pyramids are named according to the shape of their_________________
When we think of pyramids we think of the Great Pyramids of Egypt. They are actually Square Pyramids, because their base is a Square.

3. -A prism has two bases that are congruent to each other.
Prisms:
-A prism has two bases that are congruent to each other.
- The two bases in a prism, are parallel to each other.
Pyramids:
A pyramid has triangular sides (lateral faces), and either a rectangular or triangular base.
A Pyramid has one base, and is made of shapes similar to the base, that get progressively smaller until they come to a point called a vertex/apex.

4. Cross Sections
A slice of any 3 dimensional figure with a plane creates a __________
Cross sections are either taken ______________ or ____________ to the base, but they can also be taken at a_____________.   
Cross Section
Parallel
Perpendicular
Diagonal

5. Types of Cross Sections:
If a shape is cut parallel to the base, then the cross section looks just like the base.
If a shape is cut perpendicular to the base, then the cross section looks just like the lateral face.
If the shape is cut diagonally, the cross section looks like a stretched out base.

7. Parallel Cross Section
Same Shape as the base
