It's very similar to the Segment Addition Postulate. m<ABC=m<ABD + m<DBC. An angle is a figure that's formed by two rays with a common endpoint called a vertex. (the vertex will always be in the center of your angle).
Ex:
m<ABD = 37 degrees and m<ABC = 84 degrees. Find m<DBC. It might help if you draw a picture. *Remember, BD bisects (or divides) <ABC*
m<ABC=m<ABD + m<DBC
84 degrees = 37 degrees + m<DBC
-37 -37
47 degrees = m<DBC
Now try one on your own:
m<XYZ = 121 degrees and m<XWY = 59 degrees. Find m<YWZ. Drawing a picture will help.

How can I prove an angle bisector?
It depends on what is given.In general, one half of the bisected angle is proven to congruent to the other half. By the Definition of an Angle Bisector, the bisected angle can be proven bisected.---- To show that two angles are congruent:One way to prove the two angles congruent is to show that their measures are equal. This can be done if there are numbers on the diagram. 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.Given that the smaller angles correspond on a congruent or similar pair of figures in that plane and form an angle bisector, the Corresponding Parts of Congruent Figures Postulate or Corresponding Parts of Simlar Figures Postulate may be used.
What is asa postulate?
The Angle Side Angle postulate( ASA) states that if two angles and the included angle of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
What is the SAS postulate?
The SAS Postulate states if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
