Answer 1

Answer:

Ok its very easy

Step-by-step explanation:

Given: ABC is an isosceles triangle

BD is perpendicular to AC

D is the midpoint of AC

AB=BC

To Prove: ∆ABD=~ ∆CBD

Proof: In ∆ ABD and ∆CBD

AB=BC ( Given)

BD=BD ( Common)

Angle BAD= Angle BCD ( Opposite angles of

equal sides are equal)

Therefore,

∆ABD =~ ∆CBD

Hence Proved
