Detailed explanation-1: -Another Greek named Pythagoras also studied geometry. He discovered the Pythagorean Theorem which is still used today to find the sides of a right triangle.

Detailed explanation-2: -The discoveries of several Greek mathematicians, including Pythagoras and Euclid, are still used in mathematical teaching today. Important developments include the basic rules of geometry, the idea of a formal mathematical proof, and discoveries in number theory, mathematical analysis, and applied mathematics.

Detailed explanation-3: -Geometry in Classical Greece Classical geometers like Thales, Pythagoras, and later on, Plato, talked about things like eternal forms and the axiomatic method and these principals are still in use today. The Pythagorean theorem, which was developed by Pythagoras, is still an essential part of geometry today.

Detailed explanation-4: -Pythagoras (c. 570 – c. 495 BC) was credited with many mathematical and scientific discoveries, including the Pythagorean theorem, Pythagorean tuning, the five regular solids, the Theory of Proportions, the sphericity of the Earth, and the identity of the morning and evening stars as the planet Venus.
