( mathrm{ABC} ) is a right angled triangle at ( mathrm{B}, overline{B D} perp overline{A C} ) then ( (B D)^{2}=A D times ldots )

Question

Accepted Answer

Step:1 ：( (AC)^{2}=(AB)^{2}+(BC)^{2} )Step:2 ：( (AD)^{2}+(BD)^{2}=(DC)^{2}+(BD)^{2} )Step:3 ：( (BD)^{2}=AD times DC )

Answer

Step: 1 ：( (AC)^{2}=(AB)^{2}+(BC)^{2} )Step: 2 ：( (AD)^{2}+(BD)^{2}=(DC)^{2}+(BD)^{2} )Step: 3 ：( (BD)^{2}=AD times DC )

\( \mathrm{ABC} \) is a right angled triangle at \( \mathrm{B}, \overline{B D} \perp \overline{A C} \) then \( (B D)^{2}=A D \times \ldots \)
