ABC is an isoscel

Answer :

ΔABC is right triangle.


Applying Pythagoras theorem we get,


AC2 = AB2 + BC2 { AB = BC}


AC2 = 2AB2


Given that the two triangles ΔACD and ΔABE are similar.


We know that if two triangles are similar then the ratio of their areas is equal to the ratio of the squares of their corresponding altitudes.
