### sense in the lessons

In everyday life triplets are rare; people often find it hard to tell identical triplets apart. In maths, a triplet is a set of three numbers, and in geometry a Pythagorean triplet fits a right-angled triangle (3² + 4² = 5²). In music, triplets give a bouncy rhythm. Phrases: «a set of triplets», «identical triplets», «Pythagorean triplet».

### note

Countable. Triplets are three babies born together; twins are two; quadruplets («quads») are four. In maths problems, triplets are the same age, so multiply one age by 3 for the total. Triplets can be identical or not.
