is
the
polygon
that
results
from
joining
____________________
points
with
straight
lines
.
Every
triangle
has
three
____________________
(
a
,
b
and
c
)
,
three
____________________
(
A
,
B
and
C
)
and
three
____________________
____________________
(
A
,
B
and
C
)
.
The
triangles
can
be
classified
according
to
two
criteria
:
____________________
:
All
3
sides
(
a
,
b
,
and
c
)
are
equal
.
All
three
interior
angles
are
equal
.
____________________
:
They
have
two
equal
sides
(
a
and
b
)
and
a
different
side
(
c
)
Angles
A
and
B
are
equal
,
and
the
other
acute
is
different
.
____________________
:
All
three
sides
are
different
.
The
three
angles
are
also
different
.
According
to
the
measure
of
its
angles
____________________
____________________
:
They
have
all
three
acute
angles
(
less
than
90
degrees
)
____________________
:
The
interior
angle
A
is
right
(
90
degrees
)
and
the
other
two
angles
are
acute
.
____________________
angle
:
interior
angle
A
is
obtuse
(
more
than
90
degrees
)
The
other
two
angles
are
acute
The
sides
that
form
the
right
angle
are
called
legs
(
c
and
b
)
,
the
other
side
hypotenuse
The
sides
that
form
the
right
angle
are
called
legs
(
c
and
b
)
,
the
other
side
hypotenuse
.
