oh yey geometry where I can use my faulty intuition

 

AB//CD

ED//BC

AE//BD

 

Theorem (in my own words): Two triangles have the same area if they share a base and their height is presumably equal.

 

Count all the triangles that have base AB that has the other two sides joining on a point lying on line DC

 

Count all the triangles that have base DB that has the other two sides joining on a point lying on the line EA

 

Count all the triangles that have the base AD that has the other two sides joining on a point lying on.... oh wait! AD is NOT parrelel to BD. So there is only one triangle for this case.
