,
in
Δ
A
B
C
,
seg
A
D
and seg
B
E
are altitudes and
A
E
≅
B
D
.
Prove that seg
A
D
≅
seg
B
E
Open in App
Solution
Let the point of inter-section of altitudes be
x
,
in
△
D
X
B
,
∠
E
X
A
=
∠
B
X
D
(vertically opposite angles)
∠
X
E
A
=
∠
X
D
B
(Right angles)
and
A
E
=
B
D
So,
△
D
X
B
≅
△
E
X
A
and thus,
E
X
=
X
D
(CPCT)
⟶
i
and
X
B
=
X
A
(CPCT)
⟶
i
i
Adding
i
and
i
i
, we get...
B
E
=
A
D
.
Hence proved.
