**09/26**: Classwork: Math 9 Algebra baseline test | Classwork: Math 9 Geometry baseline test |

Solve the problems in the test handouts that were not done in class. In algebra, this includes placement tests from previous years. In geometry, please go over the proofs of Pythagorean theorem that we considered in class and make sure you understand the Euclid's "equal pants" proof. Go over the review topics - we will consider these briefly next Sunday. Consider and write down the solution for the cuboid problem: How many rectangular cuboids with integer sides have volume equal to 1024? In order to understand it, consider the easier, rectangle problem: How many rectangles with integer sides have area equal to 1024?
