The probability that a triangle with angles that are multiples of 30° has at least two congruent angles is 1/2. This is derived from the total combinations of angles possible for a triangle, showcasing the combinations with at least two angles being equal. Out of 12 possible configurations, 6 meet the criteria, leading to this probability.
