Question

consider a students construction on segment qt, where qr ≠ rt. what did the student most likely construct? the midpoint of segment qt the midpoint of segment rt the perpendicular bisector of segment qr the perpendicular bisector of segment qt

Explanation:

从图中可以看出，所作的线垂直于线段QT且与QT相交，符合线段垂直平分线的特征，虽然QR不等于RT，但该线依然是线段QT的垂直平分线。

Answer:

the perpendicular bisector of segment QT
