Answer:
◇(consider this sign as triangle)
◇ABC is an isosceles triangle .......given
AB=AC...........given
DB=CE............given
In ◇ABC
/_ABC= /_ ACB............angles of isosceles
triangle
Let assume their measures as x°
( of angle ABC & ACB)
From the figure,
/_ABD + /_ ABC = 180°.......linear angles
:./_ABD + x =180°
:./_ABD= 180 - x°.............(i)
/_ACE + /_ ACB =180°.........linear angles
:./_ACE + x° =180°
:./_ ACE = 180 - x°............(ii)
From (i) & (ii)
/_ABD = /_ ACE (instead of = sign use sign
of congruence)
:.◇ ABD = ◇ ACE ....by SAS test
:.AE =AD.........................consecutive side of
congruent triangle
Hence proved.
