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.
8.G.7- Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real world and mathematical problems in two and three dimensions.
8.G.8 - Apply the Pythagorean Theorem to find the distance between two points in a coordinate system
