A Pair of Vertical Angles

• These chopsticks overlapping each other contains two vertical angles (one pair in teal, the other in purple) because two angles both form a linear pair with the same angle. These vertical anfles are congruent. Chopsticks are short, frequently tapered sticks used in pairs of equal length, which are used as the traditional eating utensils of China, Japan, Korea and Vietnam. i believe that this picture is from the food industry.
