Answer:
Given in
which a line parallel to side
intersects
other two sides
and
at
and
respectively.
To prove
(1/2)
Construction Join
and
and
then draw
and
Proof Area of
So,
and
Similarly,
and
Therefore,
?(i)(1)
and
?(ii)(1)
Now,
and
are on
the same base
and between the same parallel lines
and
So,
...(iii)
(1)
Therefore, from Eqs. (i), (ii) and (iii), we have
(1/2)
Hence Proved
