Two parallel lines are cut by a transversal. If one interior angle measures 65 degrees, what does the interior angle on the same side of the transversal measure?

Correct answer to question 34 (Mathematics Knowledge): 115 degrees

Method

Interior angles on the same side of the transversal are supplementary, so they add to 180 and the other is 115. Angles that are equal to 65 in this figure are the corresponding and alternate interior ones, which is why 65 is offered.
