Core Concepts
The author challenges readers to find the radius of a circle using high school geometry knowledge and creativity, providing hints and step-by-step solutions.
Abstract
In this engaging geometry challenge, the author presents a puzzle to determine the radius of a circle. By drawing lines and applying Pythagoras' Theorem, readers are guided through a logical process to solve the problem. The solution involves constructing squares and diagonals within them to unveil the circle's radius accurately.
Stats
A 4 by 4 square has a diagonal of 4root2.
The diameter of the circle is slightly less than 2root2.
