Question

D
and BE = CD.
(a) Is ABCD ACBE?
(b) is AABC an isosceles triangle?
B
12. In the given figure, BD and CE are altitudes of A ABC​

Answer 1

Answer:

ANSWER

Given ABC is a triangle in which altitudes BD and CE to sides AC and AB are equal

In ΔADB and ΔACE

∠ADB=∠AEC=90

0

(altitudes BD and CE to sides AC and AB)

BD=CE (Given altitudes are equal)

∠BAD=∠DAB (Common angle )

ΔABD≅ΔACE [by SAS congruence]

So AB=AC

Then triangle ABC is an isosceles triangle
