ABC and BDE are two equilateral triangles such that D is the midpoint of BC .AE intersects BC in F.prove that::
- ar(triangle BDE)=1/4 ar(triangle ABC)
- ar (triangle BDE)=1/2 ar(triangle BAE)
- ar (triangle BFE)= 2ar(triangle FED)
- ar(triangle FED)=1/8 ar (triangle AFC)
- ar(triangle ABC)=2ar(triangle BEC)
- ar(triangle BFE)=ar (triangle AFD)
- ar(triangle BFE)=2ar(triangle EFD)
