They are the ones who began to study geometry in detail in the early years. Answer from Ejay Melano
Geometry was not founded by any one person. Ancient Egyptians have been used an early stage of geometry as well as the Greeks.
The Greeks started it This is a difficult question to answer since geometry has been around in one form or another as long as there has been written history. The Egyptians were making use of geometry to build pyramids even in prehistoric times. It was the Greeks, however who first began to rigorously study geometry and try to prove facts about it. Euclid was perhaps the most notable geometer of ancient mathematics and it was he who first axiomatized the subject (carefully defined the concepts crucial to geometry).
It is Pythagoras' theorem that is applicable to any right angle triangle.
