Charlotte is writing statements to prove that the sum of the measures of interior angles of triangle pqr is equal to 180°. line m is parallel to line n.

line n is parallel to line m. triangle pqr has vertex p on line n and vertices q and r on line m. angle qpr is 70 degrees. segment pq makes 35 degree angle with line n and segment pr makes 75 degree angle with line n.

which is a true statement she could write?
answer

angle prq measures 35°.

angle pqr measures 70°.

angle prq measures 70°.

angle prq measures 75°.
