What type of math did Euclid invent?

Answer 1

Euclid is often referred to as the "father of geometry" for his foundational work in the field. He systematized and organized existing knowledge of geometry in his influential text, "Elements," which covers topics such as plane geometry, number theory, and the properties of geometric figures. While he did not invent geometry itself, his axiomatic approach and logical deductions laid the groundwork for modern mathematical thought.
