Для доведення теореми Піфагора, користуючись теоремою Птолемея, потрібно відмітити, що теорема Піфагора позначає, що у будь-якому трикутнику довжина сторони, яка лежить напроти етилона (тобто гіпотенузи), дорівнює квадрату довжини інших двох сторін. Засновано на теоремі Птолемея, що периметр трикутника дорівнює сумі квадратів довжини всіх трьох сторін. Отже, якщо ми знаємо периметр трикутника, ми можемо знайти довжину гіпотенузи та квадрат довжини інших двох сторін, що рівняє довжині сторони, яка лежить напроти гіпотенузи.
