In the given figure, `angle BAC=90^(@) and AD bot BC`.then,

A

`BC*CD=BC^(2)`

B

`AB*AC=BC^(2)`

C

`BD*CD=AD^(2)`

D

`AB*AC=AD^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
In `Delta DBA and Delta DAC`, we have
`angle ADB= angle CDA=90^(@), angle ABD= angle CAD=90^(@)- angle C`
and `angle BAD=angle ACD=90^(@)- angle B`
`:. Delta DBA~Delta DAC rArr (BD)/(AD)=(AD)/(CD) rArr BD*CD=AD^(2)`
