Question

In ABC, if angle 1 = angle 2, prove that AB / AC= BD/ DC

Answer 1

this is the answer above

Answer 2

TO FIND :

In ∆ABC, if < 1=<2, prove that

AB / AC= BD/ DC

SOLUTION:

◆Given,

<1 = <2 ; here <1 = <A <B =<2

Which means ,

◆<ABC = <ACB

Thus,

◆AB = AC .

◆Refer the attachment given below

◆AD is a perpendicular bisector of BC ,

BD = BC

◆Solving,

BD = BC

BD / DC =1

◆AB = AC .

AB/AC =1.

◆Thus,

AB/AC =BD/ BC.

Hence the solution.
