 # Introduction to Euclid’s Geometry

Confused with words like Axioms, Theorems and Conjectures? Want to know what Geometry is? In this chapter, we will travel to ancient Alexandria and meet one of the most important humans in the history of the world, Euclid. We will see how Euclid developed one of the most beautiful books that have ever been written. Let us begin this journey of shapes and the history of mathematics and geometry.

Q1.: What did the Euclid discover?

A1. Euclid was one of the greatest thinkers of all time. Also, he was the one who developed many mathematical theories. But he is well-renowned for his works in geometry and inventing many of the ways we conceive of space, shapes, and time.

Q2. Why Euclidean geometry important?

A2. Euclidean geometry is scientifically important because it flagged the way for Riemannian geometry that in turn surfaced the way for Einstein’s general theory of relativity. However, after Einstein, even this belief had to be abandoned and it is now known as Euclidean Geometry.

Q3. Is Euclidean geometry correct?

A3. It is an axiomatic system, where all the theorems are derived from a small number of simple axioms. Before, the arrival of non-Euclidean geometry these axioms were considered to be obviously true in the physical world. Hence, all the theorems would be equally true.

Q4. Is Euclidean geometry used today?

A4. The modern geometry has strong ties with physics. Also, it is a vital part of new physical concepts such as string theories and the theory of relativity. Moreover, the most basic form of geometry is Euclidean geometry that we use for all shapes and measurements.
