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. - Mar 23rd 2013, 06:53 PMbjhopperRe: Similar Triangle Prooving
mark angle A w/2dots common to ABC and ADE.It follows that ACB has 3dots = to ADE

12/24 =8/AD AD =16 DB =4
