NSX Posted May 24, 2003 Share Posted May 24, 2003 Can someone check over my proof please? Thanks. I'm using the delta symbol to signify triangle Question: S is the midpoint of side QR of :delta: PQR. QT & RW are drawn perpendicular to PS or PS extended. Prove that QT=RW: Here's my sol'n: In :delta: QTS & :delta: RWS: 1. QS = RS (given) 2. Angle QTS = Angle RWS (given) 3. Angle TSQ = Angle WSR (Opp. Angle Theorem) 4. Therefore :delta: QTS :cong: :delta: RWS (Angle Angle Side) (State1, S2, S3) 5. Therefore QT=RW Thanks. It's for a hw presentation for Monday. I've attached a jpeg of what the question looks like: Link to comment Share on other sites More sharing options...
