Lines a and b are parallel.
Which of the following angles are co-interior?
Let's remember the definition of consecutive angles:
Consecutive angles are, in fact, a pair of angles that can be found on the same side of a straight line when this line crosses a pair of parallel straight lines.
These angles are on opposite levels with respect to the parallel line to which they belong.
The sum of a pair of angles on one side is one hundred eighty degrees.
Therefore, since line a is parallel to line b and according to the previous definition: the angles
are consecutive.
If one of two corresponding angles is a right angle, then the other angle will also be a right angle.
