Irregularity refers to something that does not follow a consistent pattern or rule. For example, in mathematics, an irregular shape does not have equal sides or angles, making it different from regular shapes like squares or circles. This concept can also apply to schedules, where an irregular timetable might mean that events happen at unpredictable times. In daily life, irregularity can be seen in various contexts, such as weather patterns that change unexpectedly or traffic flow that varies from day to day. Understanding irregularity helps us adapt to changes and make better decisions in uncertain situations.
