Answer 1

Is there a figure with this problem?

Answer 2

yes @mathstudent55

Answer 3

Look at this figure:

Answer 4

Angles 1 and 3 are called "alternate interior angles."
Angles 2 and 4 are also called "alternate interior angles."

There is a theorem about parallel lines cut by a transversal.
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

In this case, lines m and n are parallel. t is the transversal. You can conclude that:
1) angles 1 and 3 are congruent.
2) angles 2 and 4 are congruent.

Now apply this to your problem.
