Angle Bisectors and Perpendicular Bisectors Cont - Transcript

If a point is on the perpendicular bisector of a segment then it is equidistant from the IF endpoints of the segment C If C is on the perpendicular M B A bisector of AB CB then CA THEN

Perpendicular Bisector Theorem 1 10 08

A

M

B

Use Perpendicular Bisectors
Use the diagram to find AB
C D 5x 12 8x A B

In the diagram AC is the perpendicular bisector of DB 8x 5x 12 3x 12

x 4 Since you were asked for AB not just x AB 8x 8 4 32
