[2] Considered the "father of geometry", [3] he is chiefly known for the Elements treatise, which established the foundations of geometry that largely dominated the field until the early 19th century.
Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia.

Two fundamental theorems of elementary geometry are customarily called Thales's theorem: one of them has to do with a triangle inscribed in a circle and having the circle's diameter as one side; [55] the other, also called the intercept theorem, is about an angle intercepted by two parallel lines, forming a pair of similar triangles.
