(ii) 1/4, 1

(iii) 1/4, 1

(iv) 3/4, 3

(v) 1/2, 2

(vi) 3/4, 3

(i) starts at 10 and makes 1/2 of a revolution, clockwise?
(ii) starts at 4 and makes 1/4 of a revolution, clockwise?
(iii) starts at 4 and makes 3/4 of a revolution, clockwise?

(i) at 4
(ii) at 7
(iii) at 1

#### Question 3. Where will the hand of a clock stop if it starts from

(i) ∠a and ∠c are acute, ∠h is obtuse
(ii) ∠x and ∠z are obtuse, ∠y is acute.
(iii) ∠p is obtuse, ∠q and ∠s are acute, ∠r is reflex.

(i) 62°
(ii) 116°
(iii) 121°

(i) 315°
(ii) 235°

(i) 60°
(ii) 30°
(iii) 150°

#### Question 11. Write the measure of the smaller angle formed by the hour and the minutes hands of a clock at 7 O’clock. Also write the measure of the other angle and also state what types of angles these are.

Smaller angle is 150° (obtuse).
The other angle is 210° (reflex).
