5.1 Perpendicular and Angle Bisectors Guiding Question:
Vocabulary/Theorems • Equidistant: when a point is the same distance from two or more objects • 5-1-1: Perpendicular Bisector Theorem: If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. • XA=XB X A B Y
5-1-2 Converse of the Perpendicular Bisector Theorem: If a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of a segment. XY AB YA ~ YB X A B Y
5-1-3 Angle Bisector Theorem: if a point is on the bisector of an angle, then it is equidistant from the sides of the angle • 5-1-4 Converse of the Angle Bisector Theorem: If a point in the interior of an angle is equidistant from the sides of the angle, then it is on the bisector of the angle.
