polygon
–
a
plane
figure
with
three
or
more
sides
that
are
all
straight.
regular
polygon
–
a
polygon
which
sides
and
angles
are
ALL
equal.
Calculating
the
PERIMETER
of
regular
polygons:
The
perimeter
of
a
polygon
is
the
SUM
of
all
its
length.
•
To
find
the
perimeter
of
a
polygon,
ADD
the
length
of
all
the
sides
together.
Example:
To
find
the
perimeter
of
this
square,
we
need
to
add
the
length
of
all
its
sides:
3
cm
+
3
cm
+
3
cm
+
3
cm
=
12
cm
The
