angled
triangle

A
line
that
cuts
another;
especially,
a
straight
line
cutting
a
curve
in
two
or
more
points.

A
line
that
cuts
another:
a
straight
line
from
the
centre
of
a
circle
to
one
extremity

produced
till
it
meets
the

to
the
other
extremity.

A
line
that
cuts
another;
a
right
line
drawn
from
the
centre
of
a
circle,
which,
cutting
the
circumference,
proceeds
till
it
meets
with
a
tangent
to
the
same
circle;
the
secant
of
an
arc
is
a
right
line
drawn
from
the
centre,
through
one
end
of
the
arc,
and
terminated
by
a
tangent
drawn
through
the
other
end.

Cutting;
divivding
into
two
parts;
as,
a
secant
line.

A
right
line
drawn
from
the

tangent
drawn
from
the
other
end;
the
number
expressing
the

of
this
line
to
