               Choose the correct option.

               1) An angle whose measure is equal to one-fourth of a revolution is

                       (a) acute angle(b)   obtuse angle  (c) right angle  (d) straight angle

               2) An angle whose measure is half of a revolution is
                       (a) acute angle(b)   obtuse angle  (c) right angle  (d) straight angle

               3) An angle whose measure is equal to full revolution is
                       (a) complete angle   (b) obtuse angle (c) right angle (d) straight angle

               4) An angle whose measure is equal to 90
                       (a) acute angle(b)   obtuse angle  (c) right angle  (d) straight angle

               5) An angle whose measure is less than 90
                       (a) acute angle(b)   obtuse angle  (c) right angle  (d) straight angle



                     Answer the following questions.

               6)      What fraction of a clockwise revolution does the hour hand of a clock turn through,

                       when it goes from 1 to 10

               7)      Where will the hand of a clock stop if it starts at 5 and makes
                       3/4 of a revolution, clockwise?

               8).     Which direction will you face if you start facing

                       south and make one full revolution?

               9)      What part of a revolution have you turned through if you stand facing
                       west and turn clockwise to face east?
