Area of triangle= √3/4*a*a
½*bh= √¾*a*a
½*a*h= √3/4*a*a
h= √3/2a
Thank You!!!
Hope this will be helpful for you.

let base be 'a' cm
and half the base is a/2 cm
and hypotenus = a cm
P.G.T
(a/2)^2+h^2= a^2
h^2= a^2- a^2/4
h^2= 2a^2-a^2/4
h^2= a^2/4
h= a/2
so altitude= a/2
and half the base is a/2 cm
and hypotenus = a cm
P.G.T
(a/2)^2+h^2= a^2
h^2= a^2- a^2/4
h^2= 2a^2-a^2/4
h^2= a^2/4
h= a/2
so altitude= a/2
thank you for the answer
ok
