Students learn the angle addition postulate and the definition of an angle bisector. Students also learn the definitions of congruent angles and adjacent angles. Students then use algebra to find missing angle measures and answer various other questions related to angle bisectors, congruent angles, adjacent angles, and segment bisectors.

Use the Protractor Postulate or the Angle Addition Postulate to find the smaller angles' measures, if they are not directly marked. Then use the Definition of Congruent Angles to prove them congruent.
