Presentation transcript:

Lesson 9.1 How do you find and approximate the square root of a number? You need to find a number b such that 𝑏 2 =𝑎 Approximate a square root by finding the integer square root your number is closest to.

Lesson 9.2 How do you classify and order rational and irrational numbers? If the number can be written as a fraction, it’s rational. If it can’t be written as a fraction, it’s irrational. You can graph the numbers on a number line using approximations for square roots or you can convert all numbers to decimals.

Lesson 9.3 – 9.4 How do you use the Pythagorean theorem to solve problems? Write down the Pythagorean theorem 𝑎 2 + 𝑏 2 = 𝑐 2 Plug in the information given to you. Solve for the unknown variable.
