7. Choose true or false True or false: A pair of adjacent angles whose noncommon sides are two opposite rays that form a straight line are vertical angles.

False: A pair of adjacent angles whose noncommon sides are two opposite rays that form a straight line are a linear pair of angles

20.True or False: A ray that bisects an angle into two congruent angles is a linear pair of angles.
