The circle o is tangent to the isosceles trapezoid A2B2E2D2.

LL 1？ =? 2x is the center line, so it is easy to prove △ Ala2 △ DD2L, that is, AL=DL.

So LL 1 passes through the center of the circle, MM 1? =? 2y

LL 1？ =? MM 1？ +? LM？ +? L 1M 1？ & gt？ MM 1？

2x？ & gt？ 2y

x？ & gt？ y

S trapezoid LD2E2L 1? =? S rectangle LDEL 1? +? 2S△DD2L

S trapezoid A2LL 1B2? =? S rectangle ALL 1B? -? 2S△ALA2

So what? S trapezoid LD2E2L 1? & gt？ S trapezoid A2LL 1B2?

So what? PQ bisects the trapezoid, then PQ is set below LL 1.

2z？ & gt？ 2x

z？ & gt？ x
