8.NS.2 - Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2 the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.

8.EE.2 - Use square root and cube root symbols to represent solutions to equations of the form x2= p, where p is a rational number. 3x

8.G.6 - Explain a proof of the Pythagorean Theorem and its converse.
