How many times during a 24-hour period does the minute hand and hour hand of a 12-hour analog clock form an angle of 180 degrees?
Are there any other interesting facts about analog clocks?
Well, analog clocks are actually becoming less common and are being replaced by digital clocks. But they have been around for centuries and were originally invented in ancient times to keep track of the hours of daylight. Did you know that the minute hand wasn't added to clocks until the 1600s?
