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.
