It is known that the AD and GD are equally trisected (i.e. AB=BC=CD and DE=EF=FG) and the area of triangle ADG is 1cm^{2}. What is the area of the quadrilateral CDEH? With many thx!!!
Hello, tsuialex!
Obviously, we can't see your diagram.
I have the same question: where is H?It is known that the AD and GD are equally trisected (i.e. AB = BC = CD and DE = EF = FG)
and the area of triangle ADG is 1 cm^{2}. .What is the area of the quadrilateral CDEH?
Assuming H is the central point indicated above,Code:D o * * * * C o - - o E * * * * * * * * B o - - ♥ - - o F * * *H * * * * * * * * * A o * * * * * * * * o G
. . we note that $\displaystyle \Delta ADG$ is divided into 9 congruent triangles.
Therefore . . .
