WebJun 7, 2024 · Another useful hint that ΔABC is a right triangle is the two given sides, 12 and 16, which make up 2 of the 3 numbers that form a "Pythagorean Triple": 12, 16, 20. Pythagorean triples are 3 numbers that preserve the relationship c 2 = a 2 +b 2, meaning they can form the sides of a right triangle. WebNotice that the escribed circles that we have used in the proof of Theorem 3 were escribed on the legs of the right-angled triangle. The escribed circle on the hypotenuse of a Pythagorean triangle can only take certain integer values. This can be readily deduced from (4).
