Right triangle - Wikipedia

In geometry, Thales's theorem states that if A, B, and C are distinct points on a circle where the line AC is a diameter, the angle ABC is a right angle. Thales's theorem is a special case of the inscribed angle theorem and is mentioned and proved as part of the 31st proposition in the third book of Euclid's Elements. It is generally attributed to Thales of Miletus, but it is sometimes attributed to Pytha… WebThe Mathematics Behind It. The Pythagoras Theorem says: In a right-angled triangle, the square of a (a 2) plus the square of b (b 2) is equal to the square of c (c 2 ): a 2 + b 2 = c 2. Let's check if it does work: 3 2 + 4 2 = 5 2. Calculating this becomes: 9 + … fish lights port charlotte
