    Study Notes

    • The Pythagorean Theorem, attributed to Pythagoras, describes the relationship between the sides of a right triangle: 'a squared' plus 'b squared' equals 'c squared'.
    • The theorem applies only to right triangles, where the hypotenuse is the side opposite the right angle.
    • The two legs of the right triangle are represented by 'a' and 'b', while the hypotenuse is represented by 'c' in the theorem.
    • The Pythagorean Theorem is a useful tool to find the length of an unknown side in a right triangle when the lengths of the other two sides are known.
    • It involves squaring the lengths of the legs, adding them together, and equating them to the square of the hypotenuse.
    • The theorem can be applied algebraically to solve for the unknown side length using the formula 'a squared' plus 'b squared' equals 'c squared'.
    • Understanding the Pythagorean Theorem involves knowledge of angles, triangles, exponents, square roots, and basic algebra.- The square root of 20 can be simplified to 2 times the square root of 5.
    • A unit square cut in half along a diagonal results in a diagonal length of the square root of 2.
    • The Pythagorean Theorem can be used to find the length of an unknown side of a right triangle.
    • The Pythagorean Theorem can also be used to test if a triangle is a right triangle by checking if 'a squared' plus 'b squared' equals 'c squared'.
    • It is emphasized that practice and application of math skills are essential to effectively use the Pythagorean Theorem.
