Pythagoras, Isaac newton (Calculus, I know, but I'm not sure), and Constantine (I think)
It was Descartes.
Euclidean geometry, non euclidean geometry. Plane geometry. Three dimensional geometry to name but a few
A man who has something to do with triangles could be a geometry teacher, a musician in an orchestra, of a road sign maker. You may also be thinking of Pythagoras who invented the pythagorean theorum (A^2+B^2=C^2).
From an Arab mathematician called Al-jibra, or something very similar!
The first name of Euclid is not definitively known, as he is primarily referred to by his last name in historical texts. Euclid was a Greek mathematician, often called the "Father of Geometry," and lived around 300 BCE. His most famous work is "Elements," which systematically compiled and systematized the knowledge of geometry at the time.
Ecluid was a Greek mathematician who was also known as "The father of Geometry." He also wrote books on spherical geometry, conic sections, rigor, perspective and number theory. His name meant 'Good Glory' in Greek. Euclid also deciphered many theories and elements in science.
One prominent mathematician known for his work on 3-D shapes is Henri Poincaré. He made significant contributions to topology, particularly in understanding the properties of three-dimensional spaces. Another key figure is David Hilbert, who formulated the famous Hilbert's problems, some of which relate to the geometry of 3-D spaces. Additionally, mathematicians like William Thurston further advanced the study of three-dimensional manifolds.
Knife edge geometry refers to the shape of the cutting edges and the relief behind it. The three main types are Hollow, Taper and Flat..the name refers to the shape of the grinds which makes up the edge geometry.
Please ask the question again. This time, include the name of the mathematician.
