2. *Picturing 3-dimensional objects on a flat
surface you must distinguish their sides
*Sides are faces.
*Sides of the faces are called edges.
*A point where three faces intersect is called a
vertex.
3. *
*Prisms have two bases that are polygons.
*The bases are congruent and lie in parallel
planes.
*The shape of the bases name the prism.
4. *
*Notice the three edges intersect at each
vertex.
*Their measurements are the dimensions of the
prism.
*Length, width, and height.
*One dimension is called the depth.
5. *
*Draw a figure to represent the lower
base.
*Draw parallel and congruent line
segments from each vertex.
*Connect the vertices of the rear
base in clockwise or
counterclockwise order.
