Geometry Activity:
Draw a
Rectangular Prism
1.
Planes
ABC
and
EFG
are parallel because those
are the planes given as parallel. Planes
BCG
and
ADH
are parallel, as well as planes
ABF
and
DCG
because opposite sides of a rectangular
prism are parallel the same way opposite sides of
a rectangle are parallel.
