Given: Using the diagram below:
If l||m, then ∠3 and ∠7

Conclusion:

Justification:

Answer 1

3 and 7 are the same (as are 8 and 2) and others.

They are called alternate angles or Z angles, from the Z shape they form if you start left at l, move down then go right on m.

This is a standard theorem that holds for parallel lines.
