Pythagorean theorem
Long before Pythagoras of Samos was credited for Pythagorean Theorem, people have already noticed how the 3 sides of a right triangle have a relationship. The theorem simply says that the sum of the squares of the two sides of a right triangle will be equal to the square of the hypotenuse. A simple formula to represent which is a^{2} + b^{2} = c^{2}, where a and b are the triangle’s sides, and c is the hypotenuse.
In the first part of this chapter, we will discuss all about squares and square roots. We will be able to learn how obtain the set of prime factors that comprises a number. We will be using Prime Factorization, a process by which we list down all the factors of a certain number until we get its prime factors. Through this method, we will also be able to pinpoint numbers that are perfect squares.
For the second part, we will look at the Pythagorean Theorem more thoroughly to understand how to use it. We will be solving for the hypotenuse, or the sides based on the Pythagorean Theorem.
For the third segment, we will be looking into how to estimate a square root since not all square roots would give us whole numbers.
For the fourth part of this chapter, we will then be discussing all about Pythagorean Relationship. Now instead of just solving for the sides of a triangle we will be dealing with more complex problems like using shapes adjacent to the right triangle to solve for the value of a, b, or c.
In the last part of this chapter, we will be looking closely at how to use the Pythagorean Theorem in more real life situations and problems. In no time, you would be ready to solve problems that are related to the Pythagorean Theorem and you can check out the Pythagorean Calculator online if you want to check your answer.
