Rationalising the denominator of real numbers

This example demonstrates how to rationalize the denominator of real numbers using geometric methods. Key mathematical concepts include rationalization, conversion of real numbers to fractions, and geometric construction. The construction involves using GeoGebra commands like Point, Textfield, and variables such as m, b, n to create points, text, and input boxes. It is suitable for middle school students learning real number operations and geometric construction techniques.
