I would describe that statement, that Euclid was the first to apply for geometry, as confusing, rather than as being either true or false. People apply for jobs, they apply for loans, they apply for disability payments, they apply for grants, but they do not apply for geometry. People study geometry, they write about geometry (which is what Euclid did) and they use geometry to solve various problems, but they don't apply for geometry.
Yes
It is not known. Euclid's Elements is famous for setting out geometry in a systematic and axiomatic way, his book was by no means the first on geometry.
The purpose of Euclidean Geometry is to understand plane (2-D) and solid (3-D) geometry with the understanding that things are "flat". Around 300BC Euclid organized the current knowledge of geometry in a series called the "13 elements" . Euclid was a famous Greek mathematician. The Greeks considered geometry to be its pride and joy. They were the first to ask important questions beginning with "How and Why". Their main goals were to spread their knowledge of Geometry and answer the question relating to the purpose of Geometry. The answer, the purpose of Geometry is to understand the purpose or existence of life (mankind) itself. Geometry is not just about shapes and things that have been created by mankind. Geometry is in nature and even exists in the things we cannot see. "Geo" means Earth and "metry" comes from the word meaning measurement. So, rightfully so geometry mean the measurement of earth. I will leave you with a famous pun- Without geometry, life is pointless. ---
Nothing is known of Euclid's personal life.
Pythagoras was born around 570 BC, about 235 years before Euclid,
True
Yes
Because he was the first write a book about Geometry.
Geometry was first studied in the 3rd century B.C. by Euclid.
Because he was the first person to write a geometry book!
Yes.
He was a geometrician and he was the first person to write a geometry book.
It is not known. Euclid's Elements is famous for setting out geometry in a systematic and axiomatic way, his book was by no means the first on geometry.
It must be the book written by the great Greek teacher Euclid.
Euclid is the person credited with the invention of geometry. However the first uses of geometry are recorded to be over 5 thousand years old near the Indus Valley.
He is famous for his Elements, a presentation in thirteen books of the geometry and other mathematics known in his day.He also was the first person to study geometry.
There have been many such books, One of the first that survived is Euclid's Elements.
