### Re: BdMO National 2012: Secondary 8

@Tahmid

How can we say that

$\angle DAE+\angle ECD=180^{\circ} \Rightarrow \angle DAE+2(\angle DAC+\angle ACD)$

$\Rightarrow 3\angle DAE=180^{\circ}$

How can we say that

$\angle DAE+\angle ECD=180^{\circ} \Rightarrow \angle DAE+2(\angle DAC+\angle ACD)$

$\Rightarrow 3\angle DAE=180^{\circ}$

### Help with BDMO Problems

1. In triangle ABC, medians AD & CF intersect at point G. P is an arbitrary point on AC. PQ & PR are parallel to AD & CF respectively. PQ intersects BC at Q & PR intersects AB at R. If QR intersects AD at M & CF at N, then prove that area of triangle GMN is (A)/8 where (A) = area enclosed by PQ, PR,...
