    Re: Similar Triangle Prooving

    Hey JohnyyMal.

    Hint: Let angle DAE = x and look at the relationships between all the angles.

    One relationship for example is DAE + EDA + AED = 180 and ABC + CBD = 180. When you use these rules and collect things together, you should be able to prove the identity.
