If an angle is a right angle, its measure is 90.
If an angle measure is 90, the angle is a right angle.
A)One statement is false. If an angle is a right angle, its measure may be 180.
B)One statement is false. If an angle measure is 90, the angle may be an obtuse angle.
C)Both statements are true. The measure of an angle is 90 if and only if it is not a right angle
D)Both statements are true. An angle is a right angle if and on
