Question

In $	riangle ABC$, $\angle C = 90°$ and $D$ is the midpoint of $BC$. Then $AB^2 =$

Accepted Answer

$AD^2 + 3 BD^2$

Answer

$AD^2 + BD^2$

Answer

$AD^2 + 2 BD^2$

Answer

$2(AD^2 + BD^2)$

In △ABC\triangle ABC△ABC, ∠C=90°\angle C = 90°∠C=90° and DDD is the midpoint of BCBCBC. Then AB2=AB^2 =AB2=
