Answer:
Congruent angles
Step-by-step explanation:
Angle bisectors, divides the given angle into two equal parts
thus if value of angle is x then angle bisector will divide this angle into parts
of equal value x/2 .
_______________________
complementary angles are two angles whose sum is 90 degrees.
since we do not the value of angle we cannot say with certainty that the angles are complementary
Congruent angles are angles who have the same angular measurement.
since, in above problem we have seen that angle bisector divides the angle in two equal parts.
hence angles are equal and thus they are congruent angle.
Congruent angles is the correct answer.
_______________________________________
vertical angles are angle opposite two one another when two line cross each other.
Since in the problem line is not intersecting each other thus, angles do not qualify to be vertical angles
Supplementary angles are two angles whose sum is 180 degrees.
since we do not the value of angle we cannot say with certainty that the angles are Supplementary.
Hence correct option is Congruent angles
