a) How many degrees does the hour hand rotate through if it moves clockwise from 1pm to 3pm?


b) If the hour hand moves clockwise from 5am to 10am, how many degrees does it rotate through?


c) If the hour hand moves clockwise from 2pm to 11pm, how many degrees does it rotate through?


d) How many degrees does the hour hand rotate clockwise through from 9pm to 4am?


7. How many degrees will the minute hand of the clock rotate through in each of the following?


a) 30 minutes b) 60 minutes Measuring Angles with a Protractor


1. Estimate the size of each of these angles and then measure them using your protractor. Remember to place the base line of the protractor along one of the lines of the angle and the point of the angle on the centre point of the protractor.


c) 25 minutes d) 40 minutes


2. Have a look at this picture and find 5 different angles. Estimate the size of each angle and then measure the angle to check your estimate.
