Pythagorean Theorem is a2 + b2 = c2 if a=3 and b=4 then 32 + 42 = c2 so 9 + 16 = c2 simplifying we have 25 = c2 then square root both sides so c = 5

You learn the Pythagorean theorem.
You would use the Pythagorean Theorem when you are trying to determine the length of a side on a right triangle.ORYou might use the Pythagorean Theorem if you are carpenter or builder. A carpenter might use the Pythagorean Theorem to find the length of the hypotenuse (longest side of the triangle) or the length of the wall or roof. Use can use this methed or theorem in any building situation.
c2 = a2 + b2
The Pythagorean theorem is used to find the length of a certain side in a right triangle. If you know the length of two sides of a right triangle, you can use the Pythagorean theorem, a2+ b2 = c2, to find the length of the other side. In the formula, c is the hypotenuse, which the longest side of the triangle.
pythagorean theorem is a2 + b2 = c2 (only in right triangles) c is the length of the hypotenuse, and a and b are the lengths of the other two legs.
