Question

Brief about 5 Mathematicians(3
foreign and 2 Indian) who
contributed extensively to the world
of Geometry. Also, list their
achievements.

Answer 1

Answer:

Indian

ARYABHATA

Aryabhata was the first person to say that the Earth is spherical and it revolves around the sun & stated the correct number of days in a year that is 365. He also gave the formula (a + b) 2 = a2 + b2 + 2ab. Further, he worked on the place value system using letters to signify numbers and stating qualities.

BRAHMAGUPTA

Introduction of zero (0) to mathematics, which stood for “nothing”, was the biggest contribution of Brahmagupta. He also explained how to find the cube and cube-root of an integer and gave rules facilitating the computation of squares and square roots.

Foreign

1. Euclid

Euclid was one among the famous mathematicians, and he was known as the ‘Father of Geometry.’ His famous Geometry contribution is referred to as the Euclidean geometry, which is there in the Geometry chapter of class IX. He spent all his life working for mathematics and set a revolutionary contribution to Geometry. 

 

2. Pythagoras

‘Pythagoras theorem’ is very popular and an important mathematical formula to solve mathematical problems. Since childhood, all of us have struggled to solve mathematical problems applying the Pythagoras theorem. Pythagoras discovered this prominent theorem and he became the father of ‘Pythagoras theorem.’ Pythagoras was from Greece, but he fled off to India in the latter part of his life.

 

3. Archimedes

Archimedes was a Greek Scientist, a great mathematician, and a Physician. He also worked his entire life in search of discovering mathematical formulas that are related to Physics. The best contribution of Archimedes in mathematics is known as the invention of compound pulleys, antiquity, and screw pump. Students of class X have to study these chapters of compound pulleys and antiquity.
