Who is known as the "Father of Geometry"?

Euclid is referred to as the "Father of Geometry" primarily due to his foundational work in the field through his book, "Elements." This work, created around 300 BC, systematically compiled and organized the knowledge of geometry at that time and laid out the principles of what is known as Euclidean geometry. He established propositions, proofs, and postulates that have remained influential in mathematics for centuries.

His method of proving theorems based on previously established truths set a standard for mathematical rigor and is still a cornerstone of geometry education today. This legacy solidified his title and significance in the field, distinguishing him as a pivotal figure in mathematics.
