1 Q: In the triangle ABC, the angle ACB = 90 degrees and the angle B = 30 degrees.

So Ca = 1 2Ab, and A=60 degrees, because Cd is the midline on the side of Ab, so Cd = 1 2A, i.e., Cd = Ca

And because A=60 degrees, the inflated height of the Acd is a regular triangle, because CE is the height of the triangle ABC, that is, the height of the ACD of the regular triangle, so AE=ED

2 Q. Because the angle A + the angle ace = 90°

Angle b + angle a = 90°

So the angle ace = angle b = 30°

So ce=3, ae=1

Because ab=2ac=4

So the hole ruler ad=db=cd=2

So ed=1

So the triangle cde=2+1+3=3+3
