Question

if a/b=c/d prove that a^2+c^2/b^2+d^2=ac/bd​

Answer 1

Answer:

Given that AC=BD ....(1)

AC=AB+BC

[point B lies between A and C] ....(2)

BD=BC+CD

[point C lies between B and D] .....(3)

Substituting (2) and (3) in (10, we get:

AB+BC=BC+CD

AB+BC−BC=CD

So, AB=CD

[ if equals are subtracted from equals, the remaining are equal]
