Question

1)given-AB=CD,CD=EF
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.??

Answer 1

Transitive Axiom If a = b and b = c then a = c

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.
