Geometric proof help!

[EyesThatSparkle02]

Can someone help me with this proof? Can anyone come up with a proof that is shorter than 17 steps please?

I don't understand proofs that well so all I have to start is the given and <BAC and <BAD are right due to the definition of perpendicular...but where do I go from there...our teacher said we should have short proofs and this one should be under 17 steps preferably. Can anyone help?

I fail to see anything complicated:

Angles 1+2+3+4 = 180 degrees (make up straight line CD)
Angles 1+2 = 90 degrees (given AE perpendicular to AF)
So angles 3+4 = 90 degrees = complementary
