Answer 1

Hey Friend,
Here is your answer,

Since, ABC is a right triangle,
.
. . AB2= AC2 + BC2 ( Pythagoras Theorem)
=> AB2 = AC2 + AC2 [ BC=AC]
=> AB2 = 2 AC2.
Hope it helpful to you.
Please Mark as brainliest.

Answer 2

BC =AC ( BECAUSE ISOCELES TRIANGLE )

AS WE KNOW PYTHAGORAS THEOREM

$h { }^{2} = p {}^{2} + b {}^{2}$
H =AB
B=CB
P=AC
$ab {}^{2} = ac {}^{2} + bc {}^{2} \\ ab {}^{2} = {ac}^{2} + {ac}^{2} (ac = bc) \\ so \: ab {}^{2} = 2ac {}^{2}$
