The document discusses angles on a clock face. It notes that the angle formed at 3 o'clock and 9 o'clock is 900, which is 1/4 of the total circle. It provides equations to calculate the angle measure based on the hour and minute hands, with 30h - 5.5m used for the same side and 360 - (30h - 5.5m) for the opposite side. An example calculation for 2:20 is shown using the same side equation and for 3:40 using the opposite side equation.

1. Angles in a clock

2. A circle has 3600 angle

3. Angle formed at 3 ‘o’ clock and 9 ‘o’ clock are
same. This will be ¼ of the total angle of a circle.
That is 900

4. • The minute hand will rotate 3600 in
one hour.
Then in one minute it will rotate
360/60=60
• The hour hand will rotate 3600 in 12 ho
Then in 1 hour it will rotates 360/12=30

5. That is at 3 ‘o’ clock it is
30*3=900

6. At 4 ‘o’ clock it is
30*4=1200

7. To find the measurement of the angle

8. if it is same side we can use the eq
30h-5.5m

9. if the time is 2.20
the measure of the angle is
(30*2 – 5.5*20) = 500.

10. If it is opposite side we can use the equation a
360-(30h-5.5m)

11. if the time is 3.40 the measure of the
angle is
360 – (30*3 – 5.5*40)

12. nd the following angles in the clock
