The Pythagorean theorem, a cornerstone of mathematics for millennia, provides a method for determining unknown sides in right-angled triangles using the formula a² + b² = c². Its applications extend ...

A high school teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her students. Then Calcea Johnson and Ne'Kiya Jackson stepped up to the challenge.

The mathematics problem he solved had been lingering since 1637 — and he first read about it when he was just 10 years old. This week, British professor Andrew Wiles, 62, got prestigious recognition ...
