Analog clocks use angles to tell time. They have "hands" that rotate around the clock's "face". The position of the hands shows the time. The face of the clock is a flat disk. It will often have the numbers one through twelve on the face to make it easier to read. Analog clocks commonly have two or three hands. If it has two, there is a large hand or "minute hand" and a smaller hand, the "hour hand". Clocks with three hands also have a "second hand". This hand is usually about as long as the minute hand, but much thinner.
