What is called the bisector of an angle? Draw an obtuse angle AOB. Measure and record its value. Plot the bisector of this angle.
The bisector of an angle is a ray that exits from the apex of an angle and divides the angle into two angles with the same degree measures.
∠AOB = 150 ° (which corresponds to the condition, since 150 °> 90 °)
OM is the bisector that divides ∠AOB into equal ∠AOM and ∠MOB. ∠AOM = ∠MOB (since 150/2 = 75)
