Mathematicians
This English mathematician and physicist is often credited with the invention of calculus, but he is perhaps most well known for his three laws of motion and theory of universal gravitation.
Isaac Newton
4(x-3)2
This letter, derogatively coined as "imaginary" by René Descartes in 1637, represents the square root of -1.
i
This word describes an angle greater than 90 degrees, or a person who is a bit slow-witted.
Obtuse
This famous Greek mathematician and author of The Elements is known as the “Father of Geometry.”
Euclid
This number is equal to the product of the first four prime numbers.
210
This Greek letter, in its lowercase form, is most commonly used to represent an unknown angle in geometry and trigonometry.
θ (Theta)
This type of triangle has three unequal side lengths and angles measures.
Scalene
This French magistrate of Basque origin is best known for his Last Theorem, positing that the equation xn+yn=zn has no solution for n greater than 2, which remained unsolved until 1994.
Pierre de Fermat
One million has 6 zeros. One ___ has 15 zeros.
Quadrillion
This symbol, represented by an equal sign with a tilde (squiggly line) on top, indicates that two geometric figures have the same size and shape and are thus equivalent.
≅ (Congruent)
This 3D regular Platonic solid has four triangular faces, six edges, and four vertices.
Tetrahedron
Also known as Leonardo of Pisa, this famous Italian mathematician is best known for discovering a sequence where each number is the sum of the two previous numbers.
Fibonacci
This is the radius (in terms of pi) of a circle with area 51.
√(51/pi)
As the numbers in the Fibonacci sequence get larger, the ratio of consecutive numbers approches this number, represented by ϕ and often referred to as the "divine proportion."
Golden ratio
Honeybees use this geometric shape when constructing their hives as a way of maximizing space in a mathematically efficient way, which boasts the respectable title the "bestagon."
Hexagon
