Yes. There were mathematicians who were in geometry. In fact, anyone who contributed to our understanding of geometry was a mathematician.
The collective nouns for mathematicians are:a number of mathematiciansa set of mathematiciansan addition of mathematicians
The diagonals of any rhombus bisect each other. A square is a special kind of a rhombus.
Loomis was an American teacher and is famous for publishing, in 1940, a book entitled "The Pythagorean Proposition" which contained 370 different proofs of Pythagoras's theorem. The proofs are not his but from mathematicians over the centuries. The book contains a proof by Euclid, by the Indian mathematician, Bhaskara, by ancient Chinese, as well as by more modern mathematicians such as Legendre, Leibniz, and Huygens and by a former president of the United States, James Garfield. There are also several proofs discovered by high school students.

two different mathematicians and scientists
Pythagoras. It was proved by early Chinese mathematicians, fyi.
John P. Mullen
Imaginary numbers were discovered when mathematicians tried to solve equations of the form x^2 + 2 = 0
the concept of a regular polyhedron remained as developed by the ancient Greek mathematicians
Arithmetic progression was invented and discovered by two different mathematicians and scientists. Their names were Harvey Dubner and Tony Forbes.
Mog the neanderthal in 86,321 B.C, but he just called it "ksaa". Many years later, the greeks named it rhombus.
Study of circles. It was derived by mathematicians(Greek?) who developed an infinite series to describe it.
Many mathematical formulas were discovered by multiple mathematicians throughout history. Some notable contributors include Euclid, Isaac Newton, Leonard Euler, Carl Friedrich Gauss, and Albert Einstein, among others. It is important to note that mathematical formulas often build upon the work of previous mathematicians, and discovery is a collective effort within the mathematical community.
It has been known from very ancient times that the length of the diagonal of a unit square is not a rational number. There were no specific mathematicians who "discovered" real numbers. Furthermore, all mathematicians of any significance, contributed to our understanding of real numbers.
Omar Khayyam discovered Pascal's triangle.
