## Quick Answer: What Does R Mean In Geometry?

In maths, the letter R denotes the set of all real numbers. Real numbers are the numbers that include, natural numbers, whole numbers, integers, and decimal numbers. In other words, real numbers are defined as the points on an infinitely extended line.

## What does R represent in geometry?

## What is R * in math?

In mathematics, the notation R* represents the two different meanings. In the number system, R* defines the set of all non-zero real numbers, which form the group under the multiplication operation. In functions, R* defines the reflexive-transitive closure of binary relation “R” in the set.

## What does the big R stand for in geometry?

The set of real numbers is denoted using the symbol R or. and is sometimes called “the reals”. Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding to integers are equally spaced.
