Define the following terms:
(i) Angle
(ii) Interior of an angle
(iii) Obtuse angle
(iv) Reflex angle
(v) Complementary angles
(vi) Supplementary angles

Solution:

(i) Two rays OA and OB, with a common end-point O, form an angle AOB that is represented as AOB">AOB∠AOB.

(ii) The interior of an angle is the set of all points in its plane, which lie on the same side of OA as B and also on the same side of OB as A.

(iii) An angle greater than $90^{\circ}$ but less than $180^{\circ}$ is called an obtuse angle.

(iv) An angle greater than $180^{\circ}$ but less than $360^{\circ}$ is called a reflex angle.

(v) Two angles are said to be complementary if the sum of their measures is $90^{\circ}$.

(vi) Two angles are said to be supplementary if the sum of their measures is $180^{\circ}$
