If an argument reads:
If ,PQ ? QR, then ?PQR is a right angle. If ?PQR is a right angle, then PQR is a right triangle. If ?PQR is a right triangle with ?Q the right angle, then (PQ)2 + (QR)2 = (PR)2. then we can conclude (a) PQ ? QR (b) If PQ ? QR then (PQ)2 + (QR)2 = (PR)2. (c) If ?PQR is a right angle then (PQ)2 + (QR)2 = (PR)2. (d) All of these are valid conclusions. (e) Both answers (b) and (c) are correct.
