Question

prove that AB²-BD²=AC²-CD²​

Answer 1

Step-by-step explanation:

In fig ac=bd then prove that ab=cd.

From the following figure prove that i)AB>BD ii)AC>CD iii)AB+AC>BC.

Factorize: (ab+cd)^2 - (ac-bd)^2.

In a figure O i s the midpoint of AB and CD. ...

If AC=BD, To show that AB=CD.

prove that when AB =AC .BD^2-CD^2=2CD? ...

ABCD is quadrilateral.
