+ 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.

+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.

+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.
