Naming Prisms and Cylinders
Base of a Prism: The two congruent and parallel sides that the prism is named for. For a prism, if there are two sides that are not rectangles, these will be the bases. If all the sides are rectangles, any two of the rectangles that are parallel to each other can be considered the bases.
Base of a Cylinder: Two circles that are parallel to each other that the cylinder can rest or "sit" on.
Directions: Use your mouse to move the figures below and identify the shape of their bases. Then fill in the first page of your notes template for this lesson.
Hint: Remember that a square is a specific type of rectangle? Although there are many options for bases in the above figure, we want to pick the most specific shape as our base.
