What is the Pythagorean Theorem?

Definition: The Pythagorean Theorem

Summary

  1. We have a right triangle with the legs of 3 and 4, but we don't know the hypotenuse
  2. Remember, ALL right triangles MUST have a2+b2=c2

Notes

    1. We have a right triangle on the diagram with the legs of 3 and 4, but we don't know the hypotenuse
    1. We can use the two sides we know and the Pythagorean Theorem to find the length of the hypotenuse
    1. If a2 + b2 = c2 is true for the triangle, it IS a right triangle
    2. If a2 + b2 = c2 is NOT true for the triangle, it is NOT a right triangle
