now can you?

phi · Answer

if DE is || to CA
then the sides of the triangle are transversals

|dw:1359074409155:dw|
if the lines are parallel then the marked angles are equal "corresponding angles"
of a transversal

if the angles are all the same, the top little triangle is similar to the big triangle.

that means you want the sides to be in proportion
