Answer:
A line that splits an angle into two equal angles.
Step-by-step explanation:
The following are reasons used in the proof that the angle-bisector construction can be used to bisect any angle-
A. SSS triangle congruence postulate
B. All of the radii of a circle are congruent.
D. CPCTC - The full form is corresponding parts of congruent triangles are congruent.
In this exercise we have to use the knowledge of triangles to identify the correct alternative, so:
Letter A
The bisector is a ray inside an angle, drawn from its vertex, and dividing it into two congruent angles (angles with the same measure).
In this way we can analyze that the only alternative that corresponds to this is the letter A, since a congruent triangle has equal angles.
