A
polyhedron
is
a
____________________
dimensional
figure
whose
____________________
are
polygons
.
Some
examples
of
polyhedrons
are
____________________
and
____________________
.
The
difference
between
a
prism
and
a
pyramid
is
that
the
first
one
has
____________________
congruent
and
parallel
polygonal
____________________
while
the
second
one
has
only
one
.
The
segments
that
join
the
faces
in
polyhedrons
are
called
____________________
and
the
____________________
are
the
vertices
.
An
____________________
____________________
has
ten
faces
,
twenty
-
four
edges
and
____________________
vertices
.
A
____________________
____________________
has
six
faces
,
____________________
vertices
and
ten
edges
.
A
____________________
is
also
called
hexahedron
,
a
Platonic
solid
.
Platonic
solids
are
polyhedrons
whose
faces
are
all
____________________
polygons
.
____________________
area
is
the
sum
of
the
areas
of
the
different
faces
of
a
polyhedron
.
Flat
patterns
of
solids
are
called
____________________
.
