who discover apothem

Answer 1

An apothem is a mathematical concept that refers to the distance from the center of a regular polygon to the midpoint of any one of its sides. The discovery of the apothem is generally attributed to the Greek mathematician, Euclid, who first described it in his Elements, written around 300 BC. However, it is important to note that the concept of the apothem may have been known to earlier mathematicians in other cultures, such as the ancient Egyptians or Babylonians.
