Los Angeles Math Circle 
5/5  Junior Circle: Geometry with Proofs. Quadratic equations. (Oleg Gleizer)This time we will finish the previous handout. We will prove a few more geometric statements before switching to algebra. Some parents have asked us to teach more algebra, so here it is. We will take a first look at quadratic equations at the end of the class. Please see the handout for the previous class.
