If an obtuse angle is bisected, the resulting angles are

a- always acute
b- right angles
c- never congruent
d- always obtuse

An obtuse angle is an angle which have a measurement equal to more than 90 degrees but less than 180 degrees. This angle is found in the second quadrant. in this case, when it is divided by two or bisected, the resulting angle ranges from 45 < A < 90 hence A. always acute.
