Yuav ua li cas piv txwv ntawm ib qho perpendicular bisector?
Piv txwv 1: Nyob rau hauv ib lub pyramid, kab ntu AD yog lub perpendicular bisector ntawm daim duab peb sab ABC ntawm kab ntu BC. Yog tias AB=20 feet thiab BD=7 feet, nrhiav qhov ntev ntawm sab AC. Nws tau muab hais tias AD yog lub perpendicular bisector ntawm kab ntu BC. AC=20 feet.
