In the triangle ABC, the angle ACB is 90 degrees, AC = BC, ad is the center line of DC side, CE is perpendicular to e, and the extension line of CE intersects AB at F Find the value of (1) AE ratio de and (2) Tan angle bad

The first problem is: Method 1 ∵ AC ⊥ CD, CE ⊥ ad, ∵ CAE ⊥ DCE. [the same is the residual angle of ⊥ ADC] ∵ ace ∽ CDE, ∵ ace area / △ CDE area = (AC / AD) ^ 2. AC = BC, CD = BC / 2, ∵ AC = 2CD, ∵ ace area / △ CDE area = 4
