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?
Angle PRQ measures 35°.
Angle PRQ measures 75°.
Angle PQR measures 70°.
Angle PRQ measures 70°.
