let area of $\triangle 1=$ area of $\triangle 2=t$
and area of $\triangle 3=1$
then area of $\triangle 4=t^2$
we have area of $\triangle 3 +$ area of $ \triangle 4=t^2+1 \geq$ area of $\triangle 1+$ area of $\triangle 2=2t$
$(AP\geq GP)$
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
