Blaise Pascal, the French mathematician, was born in Clermont-Ferrand, France on June 19, 1623. Some of his most well-know ideas are Pascal's triangle, Pascal's law, and Pascal's theorem.

de Moirve's theorem, Pascal's triangle, Pythagoras triangle, Riemann hypothesis, Fermat's last theorem. and many more

In projective geometry, Pascal's theorem (also known as the Hexagrammum Mysticum Theorem) states that if an arbitrary six points are chosen on a conic (i.e., ellipse, parabola or hyperbola) and joined by line segments in any order to form a hexagon, then the three pairs of opposite sides of the hexagon (extended if necessary) meet in three points which lie on a straight line, called the Pascal line of the hexagon. The theorem is valid in the Euclidean plane, but the statement needs to be adjusted to deal with the special cases when opposite sides are parallel.

The coefficients of the binomial expansion of (1 + x)n for a positive integer n is the nth row of Pascal's triangle.
