I^22 equals to -1 since i^2 is negative one
Your absolute value cannot be negative.
we know that
<u>Alternate interior angles</u> are two interior angles which lie on different parallel lines and on opposite sides of a transversal. Alternate interior angles are congruent
see the attached figure with letters to better understand the problem
in this problem
the parallel lines are the lines a and b
the transversal line is the line c
so
the alternate interior angles are the Angle
and Angle 
m∠3=m∠6
therefore
<u>the answer is the option</u>
Angle
and Angle 
There are many solutions, and that's an understatement. There are actually an infinite number of solutions.
