Use the Pythagorean Theorem. The Pythagorean Theorem is a special property of right triangles that has been used since ancient times. It is named after the Greek philosopher and mathematician Pythagoras who lived around 500 BCE. Remember that a right triangle has a 90° angle, which we usually mark with a small square in the corner.The Pythagorean theorem states that “In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.”. We can illustrate this idea using the following triangle: In this triangle, the Pythagorean theorem is equal to. { {c}^2}= { {a}^2}+ { {b}^2} c2 = a2 +b2.8-1 Additional Practice Right Triangles And The Pythagorean Theorem ...
