ABC is a right angled triangle , AD is perpendicular to the hypotenuse BC if AC = 2AB ,
then the value of BD is

• ans is BC/5

• in trng ABD and trngl ACD
  angle ADB = angle ADC
  AD =AD
  hence trng ABD ~ trng ACD
  CD/BD=AC/AB
  ADDING 1 BOTH SIDES
  CD/BD +1 = AC/AB+ 1
  BC/BD= AC + AB /AC
  BD= BC/3

• ans. ABsqrt(5)/2
  bc^2=ab^2+ac^2
  =ab^2+4ab^2=5ab^2
  then bc=sqrt(5)*ab
  then bd=bc/2=sqrt(5)*ab/2

• Answer is not Bc/3.
  Angle bad not equal to dac, but Angle bad equal to dac.
