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.
False: A ray that bisects an angle into two congruent angles is an angle bisector.
10. Choose true or false True or False: The set of points between the two sides of an angle is an angle bisector.
False: The set of points between the two sides of an angle is the interior of the angle
5. Choose true or false. True or false: set of points outside an angle is a supplementary angle.
False: The set of two points outside an angle is the exterior angle.
2. Choose true or false True or false: Two angles that share a common vertex and one common side but no common interior points are vertical angles.
False: Two angles that share a common vertex and one common side but no common interior are adjacent angles.
1. Choose true or false True or false: the common endpoint of the rays of an angle is called a vertex.
True: The vertex is the common endpoint of the rays of an angle.
15.True or false: Two nonadjacent angles formed by two intersecting lines are vertical angles
True: Two adjacent angles formed by two intersecting lines are vertical angles
19.True or False: Two angles in which the sum is '90^@ are complementary angles
True: Two angles in which the sum of their measures is '90^@' are complementary
13.Choose true or false True or false: an angle is a formed by two rays with a common endpoint
True: an angle is a figure formed by two rays with a common endpoint
12.Choose true or false. True or False: Two angles in which the sum of the measure is '180^@ are supplementary angles.
True: two angles in which the sum of the measure is '180^@ are supplementary angles
