Start with: a2 + b2 = c2. Put in what we know: 12 + 12 = c2. Calculate squares: 1 + 1 = c2. 1+1=2: 2 = c2. Swap sides: c2 = 2. Square root of both sides: c = √2. Which is about: c = 1.4142... It works the other way around, too: when the three sides of a triangle make a2 + b2 = c2, then the triangle is right angled.
The Pythagorean theorem describes a special relationship between the sides of a right triangle. Even the ancients knew of this relationship. In this topic, we’ll figure out how to use the Pythagorean theorem and prove why it works. Constructing triangles. Construct a right isosceles triangle. Construct a triangle with constraints.
The Pythagorean theorem is a cornerstone of math that helps us find the missing side length of a right triangle. In a right triangle with sides A, B, and hypotenuse C, the theorem states that A² + B² = C². The hypotenuse is the longest side, opposite the right angle. Created by Sal Khan. Questions.

The Pythagorean theorem states that if a triangle has one right angle, then the square of the longest side, called the hypotenuse, is equal to the sum of the squares of the lengths of the two shorter sides, called the legs. So if a a and b b are the lengths of the legs, and c c is the length of the hypotenuse, then a^2+b^2=c^2 a2 +b2 = c2.
According to the definition, the Pythagoras Theorem formula is given as: Hypotenuse2 = Perpendicular2 + Base2. c2 = a2 + b2. The side opposite to the right angle (90°) is the longest side (known as Hypotenuse) because the side opposite to the greatest angle is the longest.
3 days ago · 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.
Oct 24, 2022 · However, one of the most famous theorems in all of mathematics does bear his name, the Pythagorean Theorem. PYTHAGOREAN THEOREM Let c represent the length of the hypotenuse , the side of a right triangle directly opposite the right angle (a right angle measures 90º) of the triangle.
