1.5 Segment & Angle Bisectors. Goals:. Students will understand geometric concepts and applications. Bisect a segment. Bisect an angle. Remember!. Congruent means,… equal to each other!. Midpoint. The point that bisects a segment. Bisects ? splits into 2 equal pieces. 12x+3=10x+5
Students will understand geometric concepts and applications.

A M B
BD is an angle bisector of <ABC.
* If they are congruent, set them equal to each other, then solve!
x+40 = 3x-20
40 = 2x-20
60 = 2x
30 = x
