Open your books to page 176. Do question 23 A
A. It is given that line QR is perpendicular to line PQ and line PQ is parallel to line RS so line QR is perpendicular to line RS by te perpendicular transveral theorem. It is given that line PS is parallel to line QR. Since line QR is perpendicular to line RS, Line PS is perpendicular to line RS by the perpendicular transversal theorem
