It was invented by a mathematician named Pascal.
Pascal's triangle was invented by Blaise Pascal (1623-1662) in 1653. Although it has been named after blaise pascal, there have been traces of the triangle, long before Blaise Pascal was born. It is belived that the Persians and the Chinese had been using it to find the square and cube root of numbers. Whoever asked this question is a complete idiot, because the answer is in the question.
he invented the pascal triangle . it is a triangle where every two numbers add up to the number below them while there are all 1's going all the way down each diagonal side of the triangle. he also invented the first mechanical calculator machine.
The triangle was not invented. It is the result of observations of physical properties.
