prove-AB-EF (in 5 steps that show why it is corect; i.e two-column proof)

2)Given-<2=<3, <4=<5

prove-<1 is supplementay to <6

(in 3 steps, with the two column proof)

TWO-COLUMN PROOF LOOKS LIKE THIS....

STATEMENT: REASON:

1.AB=CD,CD=EF 1.Given

2.?? 2.??

3.?? 3.??

4.?? 4.??

5.AB=EF 5.??

So it seems to me to be two steps, not five.

You second makes no sense, it does not indicate any relationship with <1 and any other angle.
