Angle and Segment Bisector

What is a line segment or ray drawn from a vertex that divides the angle into two congruent angles?

• Median of a Triangle

• Altitude of a Triangle

• Perpendicular Bisector of a side of a Triangle

• Angle Bisector

• Midpoint of a Line Segment

Line l bisects the segment. Find the lengths of AN and AB.

• AN = 9.2, AB = 9.2

• AN = 9.2, AB = 18.4

• AN = 18.4, AB = 9.2

• AN = 18.4, AB = 18.4

Ray QS bisects <PQR. Find the measure of <RQS.

• m<RQS = 149

• m<RQS = 298

• m<RQS = 150

• m<RQS = 74.5

Find the measures of <EFJ and <JFG.

• m<EFJ = 90, m<JFG = 90

• m<EFJ = 45 m<JFG = 45

• m<EFJ = 180, m<JFG = 180

• m<EFJ = 45 m<JFG = 90
