WHERE
NAMES HAPPENED
GEOMETRICAL
FIGURES?
Almost all the names of geometric figures are of Greek origin, as is the word geometry itself, which comes from the Greek word γεωμετρία (geometry) - land surveying. However, these words entered the Russian language not directly from Greek, but through the Latin language.
The word cone is the Latin form of the Greek word zhvonos (konos), meaning pine cone.
The word cylinder comes from the Latin word cylindrus, which is the Latin form of the Greek word xυλινδρος (kylindros), meaning roller, roller.
The word prism is the Latin form of the Greek word prіσμα (prisma) - sawn (meaning a sawn log).
The word sphere is the Latin form of the Greek word σφαιρα (sphaira) - ball.

The word primada is the Latin form of the Greek word puramis (puramis), which the Greeks called the Egyptian primids; this word comes from the ancient Egyptian word “purama,” which the Egyptians themselves called these primitives. Modern Egyptians call primids the word “ahram”, which also comes from this ancient Egyptian word.
The word trapezoid comes from the Latin word trapezium (trapezium) - the Latin form of the Greek word trapezium (trapezion) - table. From the same root comes our word “meal”, which means table in Greek.
The word rhombus comes from the Latin word rombus (rhombus) - the Latin form of the Greek word rotsμβος (rombos), familiar to the tambourine. We are accustomed to the fact that a tambourine has a round shape, but tambourines and melli are also shaped like a square or diamond, as evidenced by the images of “tambourine” on playing cards.
Directly from the Latin language we borrowed the words point, sometimes used in the meaning of “dot” (hence “dotted line”) and line.
The word point comes from the Latin word punctum (punctum) - prick; The medical term “puncture” comes from the same root.
The word line comes from the Latin word linea (linea) - linen (meaning linen thread). Our word “linoleum”, which originally introduced industrial linen, comes from the same root.
Thus, all the names of geometric figures of the first initial were the names of specific objects that had a shape more or less close to the shape of a given figure.
