This is a clock but instead of numbers it has angles that is congruent to another angle on the clock. The angles drawn over in green are two congruent angles. These two angles are congruent because they are both next to the 180 degree angle. Clocks are found in almost every store and in schools, business places, houses, etc. It is used to tell time.
