Angles congruent, and similar. Parallel lines
Angle m<5 is at upper right
You can see is 90 degrees, rectangle angle
Angle m<5 is between 2 perpendicular lines
So then angles 1 and 4 are not answers, because they below to non parallel lines.
Angles 9 and 12 are equal to to m<5 ,because they below to perpendicular lines
Then answer are options C) and D)
