The hands of the clock form one 180° straight line every hour other than between the timing of 5’o o'clock and 6’o o'clock. Accurate observation and evaluation of the watch provide an idea that between 5 and 6 the hands form a straight line of 180° exactly at 6 o’clock and thus, it cannot be the one that takes place between 5 o’clock and 6 o’clock. Rather, it is contemplated to be a straight line made between 6 and 7 o’clock.Hence, the hands of a clock form 180o straight lines 11 times in 12 hours and thus generalizing it for 24 hours (a day’s time), the hands form 22 consecutive lines of 180° in 24 hours.
