A. Definition of Angle Bisector
B. Segment Addition Property
C. Definition of Congruent Angles
D. Transitive Property

The following property: If a = b and b = c, then a = c. One of the equivalence properties of equality. Note: This is a property of equality and inequalities.

Congruent Angles have the same angle (in degrees or radians). That is all. These angles are congruent. They don't have to point in the same direction. They don't have to be on similar sized lines.

The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.Jan 4, 2016

The (interior) bisector of an angle, also called the internal angle bisector (Kimberling 1998, pp. 11-12), is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.
