Then the hypotenuse formula, from the Pythagoras statement will be;c = √(a2 + b2). 2. Pythagoras theorem states that the square of the hypotenuse of a right-angled triangle is equal to the sum of the square of its base and height. This theorem is represented by the formula. The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. Given: A right-angled triangle ABC, right-angled at B. The theorem is named after a greek Mathematician called Pythagoras. Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2. The Pythagorean Theorem states that in any right triangle, the sum of the squares of the lengths of the triangle’s legs is the same as the square of the length of the triangle’s hypotenuse. One begins with a, …a highly commendable achievement that Pythagoras’ law (that the sum of the squares on the two shorter sides of a right-angled triangle equals the square on the longest side), even though it was never formulated, was being applied as early as the 18th century. If we are provided with the length of three sides of a triangle, then to find whether the triangle is a right-angled triangle or not, we need to use the Pythagorean theorem. The Pythagorean theorem was generalised by Euclid in his Elements: 1. The Pythagorean Theorem allows you to work out the length of the third side of a right triangle when the other two are known. Thank you byjus!! Let us understand this statement with the help of an example. The formula for Pythagoras, for a right-angled triangle, is given by; c2=a2+b2, The hypotenuse is the longest side of the right-angled triangle, opposite to right angle, which is adjacent to base and perpendicular.
