Congruent Angles and Segments

Congruent Angles and Segments

Review and Prep for Midterm Exam

Segment Addition Postulate

Use the Segment Addition Postulate to find the measure of line segment AB and ling segment BC.

Angle Addition Postulate

Use the Angle Addition Postulate to find the value of x, then determine the measure of each angle.

Deep Dive

Use the Segment Addition Postulate to find the value of x, the measure of line segment IJ, and the measure of line segment HK. Are there any congruent segments?

Midpoint of a Segment

If point G is the midpoint of line segment FH, determine the value of x, and the measure of line segment FH. Prove your answer using the Segment Addition Postulate.

Segment Bisectors

A segment bisector is a line or line segment that bisects (divides into two congruent parts) a line segment.

Segment Bisectors

Segment Bisectors intersect line segments at their midpoints. In this example, line segment AB is bisected by line k at M, so line segment AM is congruent to line segment MB.

Applying Segment Bisectors

Line PQ bisects line segment AB at its midpoint M. Determine the value of x, then find the measure of line segments AC and CB.
